For a conventional SDR channel, use H.264 video with AAC audio over RTMPS as the practical starting point for 24/7 YouTube live streaming in India. It is not an India-specific rule, but it is a straightforward combination with broad encoder support and settings that are easy to test.
YouTube also accepts H.265, commonly called HEVC, and AV1 for live ingestion. The right choice depends on whether your encoder supports the codec continuously and whether your internet connection can sustain the selected bitrate with headroom.
Start with a practical SDR baseline
For a devotional channel, bhajan loop, lofi station, local news loop or study stream, begin with standard dynamic range rather than HDR. Use H.264 for video, AAC for audio, RTMPS for transport, constant bitrate encoding, and a two-second keyframe interval. For ordinary SDR, YouTube’s guidance uses Rec. 709 colour and 8-bit depth.
This baseline is useful because it separates the important decisions. You are not trying to solve codec efficiency, HDR colour management and unusual hardware support at the same time. You are creating a stream that your encoder can produce for hours, that your connection can carry without repeated drops, and that YouTube can process into viewer playback formats.
A sensible first configuration might be 1080p at 30 frames per second for a channel with modest motion, such as a still devotional image with changing text or a study scene. If your source contains rapid movement, camera motion or animated graphics, 60 fps may be useful, but it increases the amount of video data and the work done by the encoder.
YouTube’s live encoder settings list 10 Mbps as the recommended H.264 bitrate for 1080p30, 12 Mbps for 1080p60, 4 Mbps for 720p30 and 6 Mbps for 720p60. Treat these as platform guidance, not as a guarantee that a particular broadband connection will remain stable at that rate.
For a small operator, a lower resolution that remains stable is usually more useful than a higher resolution that drops frames overnight. If your source is a 720p recording, sending it as 1080p does not create extra detail. It can increase encoding and upload work without improving the underlying picture.
India does not have a separate codec requirement in the official guidance reviewed for this article. Your ISP, local network, route to YouTube and time of day can affect the result, so choose the format from the equipment and connection you actually have rather than from the country label.
Compare the codecs YouTube accepts for ingest
YouTube accepts H.264, H.265 and AV1 video for RTMP or RTMPS ingestion. They are not interchangeable in practical terms. Each needs an encoder that can produce it reliably, and each may place a different load on the hardware running your channel.
| Codec | Where it fits | Main question before using it |
|---|---|---|
| H.264 | Straightforward SDR baseline with broad support | Can the encoder maintain the chosen resolution, frame rate and bitrate continuously? |
| H.265 or HEVC | A possible alternative where the encoder and workflow support it | Does YouTube ingest work correctly with your encoder, and is the saved upload demand worth the added complexity? |
| AV1 | A newer ingest option supported by YouTube | Can your hardware or software encode AV1 for a continuous stream without errors or excessive workload? |
H.264 remains a practical default for a 24/7 channel because the complete chain is familiar: source file, encoder, stream settings, monitoring and troubleshooting. That does not make it the best choice for every encoder. A newer machine with dependable AV1 hardware encoding may make a different choice reasonable, while an older computer may struggle with it.
HEVC can be attractive when your workflow supports it and the resulting settings suit your upload capacity. However, a codec that looks efficient on paper is not automatically the best operational choice. If the encoder overheats, produces errors or cannot maintain its output overnight, the theoretical saving is of little value.
AV1 has the same practical qualification. YouTube lists it as an accepted live-ingest codec, but acceptance by the platform does not mean that every laptop, desktop or VPS can encode it continuously. Check the encoder’s output options, hardware acceleration and error logs before building a channel around it.
Do not choose a codec because you expect viewers in India to receive that same codec unchanged. The codec you send is the ingest format. YouTube processes the live input for playback, and viewers may receive a different stream format depending on their device, connection and selected quality.
If your main question is specifically about HEVC, the H.264 versus HEVC guide for 24/7 loops gives you a more focused comparison. Keep the same test standard here: the format must work for the entire operating period, not merely for a short preview.
Choose RTMPS and sensible audio settings
Use RTMPS where your encoder supports it. It provides an encrypted connection for the live feed between the encoder and YouTube. You will normally enter the YouTube stream key and the appropriate server details in the encoder, then confirm that the transport is set to RTMPS rather than ordinary RTMP.
YouTube’s RTMPS guidance explains the platform’s setup requirements. Follow the current instructions shown there if your encoder presents several server or encryption choices. A small difference in a pasted server address or stream key can prevent a perfectly good video file from reaching the channel.
For audio, AAC is the sensible default for this use case. YouTube also lists MP3 for RTMP and RTMPS audio, while AAC is required for 5.1 surround sound. Most devotional, ambience, news-loop and study channels do not need surround sound, but AAC still keeps the baseline simple and familiar.
Set the audio sample rate and channel layout consistently in the encoder and source workflow. Avoid changing audio settings while the broadcast is live unless you have a clear reason. A video that continues running with broken or silent audio is still a failed result for a music, bhajan or spoken-news channel.
Pay attention to the total bitrate, not only the video number. The audio bitrate is added to the video bitrate, along with any small amount of stream overhead. YouTube’s streaming advice states: “The total bitrate you're streaming cannot exceed the amount of upload bandwidth available.” This is why a speed test and a margin below the connection’s best result matter.
For a looping channel, also check that the source audio is not clipping at the beginning or end of each file. Codec selection cannot repair a source that has abrupt cuts, different loudness between tracks or long periods of silence. Those are production problems, and they should be corrected in the file or playlist before you diagnose the network.
Check encoder support and workload
Your encoder is the part of the chain that converts the source into the chosen video codec, frame rate, resolution and bitrate. It may be desktop software, a hardware appliance, a rented virtual machine or a cloud workflow. The label on the encoder is less important than whether it supports your exact combination of settings.
Before starting the channel, check five things:
- The encoder can output H.264, H.265 or AV1 as required.
- It can send the selected codec through RTMPS to YouTube.
- It supports constant bitrate and the required keyframe interval.
- It can keep the source playing without freezing when the playlist reaches its end.
- It can maintain the output without sustained CPU, GPU, memory or thermal problems.
Hardware encoding and software encoding have different trade-offs. Hardware encoding can reduce the load on a computer’s main processor when the device has a suitable encoder. Software encoding may expose more controls or work on systems without the relevant hardware, but it can use more CPU. Neither route is automatically reliable for every machine.
Watch the system while a private or unlisted test runs. A CPU reading that looks acceptable for a few minutes may not tell you whether the system will remain stable through a warm afternoon or after other scheduled tasks start. Check for encoder warnings, missed frames, audio drift and changes in output bitrate.
A VPS can be convenient when you want the computer at home switched off, but it does not remove the need to check codec support and sustained workload. The best affordable VPS options for a 24/7 YouTube stream are only useful if the selected machine can encode your chosen format continuously and has suitable upload capacity.
For operators who do not want to maintain a computer or VPS throughout the night, StreamNeo removes the specific task of keeping the local playback and broadcast process running: you upload the video, add the YouTube stream key, and the cloud broadcast continues while your own computer is off, with automatic monitoring and restart if the stream drops. You still need to prepare the file, check the channel and confirm that the content is suitable for your audience.
Do not treat an automatic restart as a substitute for checking the cause of a failure. A wrong stream key, unsupported codec, unavailable source file or copyright issue will not be solved simply by restarting the same configuration.
Test sustained upload reliability
A speed-test result is a measurement of a moment, not a promise about an all-night broadcast. YouTube recommends running a speed test to check your upload bitrate, and its advice also recommends leaving 20% headroom. Use the actual connection and the actual stream settings when you test.
Suppose your encoder is set to the recommended H.264 bitrate for 1080p30. The relevant question is not whether a speed-test page briefly displays a larger upload figure. The question is whether the connection can carry the complete stream, including audio and overhead, while other activity is accounted for and the recommended margin remains available.
Test from the location where the encoder will run. A home connection in one room may behave differently over Wi-Fi than over an Ethernet cable. A VPS may have different capacity and route characteristics from the broadband connection used to prepare the source. If the test setup is not the production setup, record that limitation instead of assuming the results transfer exactly.
Run an unlisted test using the final resolution, frame rate, codec, audio and bitrate. Let it continue long enough to expose ordinary problems such as a router changing connection state, a scheduled backup consuming upload capacity or an encoder gradually falling behind. The test does not need to be public to be useful.
During the test, monitor YouTube’s stream health and the encoder’s own statistics. Look for dropped frames caused by network conditions, skipped or delayed frames caused by encoding, and audio problems caused by the source or encoder. These are different failure categories and need different fixes.
If the connection is unstable, first reduce the demand. Moving from 1080p60 to 1080p30, or from 1080p30 to 720p30, may create a more workable stream. You can also remove other upload activity, use a wired connection and ask the ISP about recurring faults. Do not increase the bitrate merely because the picture looks soft while the connection is already losing data.
The dropped-frames troubleshooting guide can help you separate network drops from encoder or source problems. Keep a short record of the test settings, time, connection used and observed warnings so that you can compare a change against the original result.
Plan for a stream that runs beyond 12 hours
A 24/7 channel has an archive problem as well as an ingest problem. YouTube says that if a live stream exceeds 12 hours, it may not be captured at all. That means continuous live availability should not be described as a guaranteed complete YouTube replay.
YouTube also notes that DVR rewind can be limited or unavailable on streams longer than 12 hours. A viewer may be able to watch the current broadcast while being unable to move back through the whole day. If people need to revisit a prayer, lesson, news item or music segment, plan a separate recording or upload strategy.
YouTube recommends recording a local archive as a backup. For a channel operated from a home computer, that recording must have enough storage and must not compete with the encoder for resources. For a cloud workflow, decide where the original file or an independent recording will be kept before you begin.
If you are trying to keep a devotional broadcast running past the 12-hour point, the guide to 24/7 devotional streams past 12 hours covers the operational issue separately. It does not change YouTube’s archive caveat, so preserve an independent copy if the full feed matters.
A long stream also increases the value of a repeatable source. Check that the playlist returns cleanly to its first item, that the audio does not accumulate silence, and that the source does not require a person to click a dialogue box after a file ends. Test the complete loop before making it public.
Understand what viewers actually receive
The ingest codec is the format your encoder sends to YouTube. It is not necessarily the format delivered unchanged to every viewer. YouTube says it automatically transcodes live streams into different output formats for viewers.
That processing allows people with different devices and connections to select an appropriate playback quality. A viewer on a phone may choose a lower quality than someone watching on a large screen with a stable broadband connection. Your job is to provide a clean, stable source for YouTube to process, not to predict one identical codec for every audience member.
This distinction also explains why changing from H.264 to AV1 does not automatically make the picture look better to every viewer. The visible result depends on the source quality, resolution, frame rate, bitrate, motion, YouTube’s processing and the viewer’s selected playback stream.
For the same reason, do not upscale a low-resolution source and expect transcoding to restore missing detail. A 720p devotional image remains limited by the source even if the encoder sends a 1080p output. Improve the original asset, then choose settings that your encoder and connection can sustain.
Colour settings deserve the same care. A conventional SDR workflow should follow the Rec. 709 and 8-bit guidance rather than mixing HDR settings into a normal stream. HDR is a specialised workflow with separate requirements, including HEVC considerations, and should be tested independently rather than adopted casually for a general 24/7 channel.
Frame rate is also a source decision. The 30fps versus 60fps live-stream comparison is useful when you are deciding whether a moving camera, animated background or scrolling news layout benefits from 60 fps. For a mostly static scene, 30 fps can be the simpler starting point because it reduces sustained encoding and upload demand.
A practical setup sequence
Use this order when preparing the broadcast:
- Inspect the source. Confirm its native resolution, frame rate, colour type, audio channels and whether it loops cleanly.
- Choose SDR unless you have a tested reason to use HDR. Start with Rec. 709 and 8-bit settings.
- Select H.264 video and AAC audio unless your encoder has a specific, tested reason to use H.265 or AV1.
- Set RTMPS, constant bitrate and a two-second keyframe interval. YouTube says the keyframe interval should not exceed four seconds.
- Select a resolution and frame rate that match the source and the connection. Use YouTube’s current bitrate table as guidance.
- Run a speed test and leave upload headroom. Include audio and other activity when judging the connection.
- Test the exact configuration as an unlisted stream. Watch encoder workload, stream health, dropped frames and audio.
- Prepare an independent recording if the complete 24/7 feed must be preserved.
- Start the public stream only after the test completes without unexplained warnings.
Keep a copy of the working settings. If the stream fails later, change one variable at a time. Replacing the codec, bitrate, resolution and connection together makes it difficult to know which change helped.

FAQ
Is H.264 the only format YouTube accepts for a 24/7 stream?
No. YouTube also lists H.265 or HEVC and AV1 for live ingestion through RTMP or RTMPS. H.264 with AAC remains a practical SDR baseline, but the best choice depends on encoder support and sustained reliability.
Does India require a special codec for YouTube live streaming?
The official guidance reviewed here does not establish a separate India-specific codec requirement. Choose the format based on your encoder, source and actual upload connection, then test the complete setup.
What bitrate should I use for 24/7 streaming?
Use YouTube’s current encoder guidance as a starting point and test it against your real upload capacity. For H.264, the listed recommendations include 10 Mbps for 1080p30 and 6 Mbps for 720p60, but a stable lower-demand stream is preferable to a higher setting that drops data.
Will YouTube keep a complete archive of a 24/7 broadcast?
Not necessarily. YouTube says a stream exceeding 12 hours may not be captured at all, and DVR rewind may be limited or unavailable on very long streams. Record an independent local or otherwise separate archive if preserving the complete feed matters.
