If your Hindi YouTube playlist stream stops when FFmpeg reaches a Devanagari filename, first identify how that file reaches FFmpeg. The -safe 0 remedy applies to the FFmpeg concat demuxer, not to every playlist or direct input path.
A Devanagari filename is not, by itself, proof of an FFmpeg defect. Check the exact path and the error, then decide whether the failure is in the shell or application handing over the path, the concat demuxer’s safety check, or the media file itself.
Identify the playlist or input format
Start with the command or application configuration that launches FFmpeg. Is it opening a media file directly, reading a text file of file entries, or consuming a playlist made for another format? The word “playlist” is used for several different things, and the options for one format should not be copied blindly to another.
A direct input might look like ffmpeg -i 'भजन.mp4' .... In that case FFmpeg is being asked to open the named media file; there is no concat playlist safety check just because the filename contains Hindi characters. A shell, script, service, or graphical application may still be passing a different path than you expect. Confirm what command is actually run and what text it supplies as the input path.
An FFmpeg concat script is a text file, often named something like playlist.txt, with directives such as file 'गीत.mp4'. FFmpeg’s concat demuxer reads that script and then opens the files it names. The separate script filename and the media filenames inside it both need to be correct. FFmpeg documents the concat demuxer and its script syntax in its concat demuxer reference.
Other playlists have their own syntax and handling rules. If the file contains an M3U-style list, is generated by a media player, or is being passed through a wrapper, find out which demuxer or application is interpreting it before trying a concat option. The same word on a screen does not tell you which FFmpeg input path is active.
Keep the YouTube destination separate from this diagnosis. A stream can stop before it sends useful media to YouTube because a local input cannot be opened; reconnecting the live output will not correct that input failure. For a different failure layer, such as reconnect behaviour after an established broadcast disconnects, see how to reconnect FFmpeg automatically when a YouTube stream disconnects.
Check whether FFmpeg is reading a concat script
Look for -f concat in the command and a text file immediately following the relevant -i, for example -f concat -i playlist.txt. That is a strong indication that FFmpeg is using the concat demuxer. Then inspect the text file itself: concat scripts use file directives to name each segment, and may contain other directives as well.
Do not infer concat use merely because the source material is a sequence of videos. A script or application can instead open each file separately, pass one file as an input, or use a different playlist demuxer. The important question is what FFmpeg receives in this invocation, not how the playlist is described in a channel dashboard.
If you have access to the command, record the exact input options and paths before changing anything. If a streaming application constructs it for you, inspect its logs, configuration, or generated command where available. A visible playlist name may not be the actual script passed to FFmpeg. If the tool hides that detail, check its documentation or diagnostics rather than adding flags on a guess.
Also check the installed build with ffmpeg -version if its behaviour seems to differ from the documentation. The available FFmpeg documentation describes the option, but your local version, operating system, shell, and application are part of the path handoff. A small difference there can explain why a command copied from another machine does not behave the same way.
Understand the concat safe-path check
The concat demuxer’s safe option controls whether paths in the script pass a portability check. The documented default is safe=1. Under that setting, concat rejects paths that do not meet its specified safe-path rules, which use a restricted portable character set. A Devanagari character in a concat entry may therefore be rejected by that check, even though this does not establish that FFmpeg cannot open Devanagari filenames in general.
This distinction matters because the check belongs to the concat demuxer. It is not a universal Unicode switch for FFmpeg, and it does not tell you whether a direct path, a shell, or a separate playlist format can handle the same filename. The FFmpeg command-line documentation describes how input options and inputs are supplied; the active input format determines which demuxer-specific options make sense.
For a concat script, inspect whether the error explicitly mentions an unsafe file name or path. That clue is more useful than the visual fact that the filename is in Devanagari. If the error instead says no such file, permission denied, invalid data, or reports a codec or stream problem, do not assume the safe-path filter is responsible.
Quoted or escaped paths still matter. The concat documentation allows special characters and spaces to be handled with quoting or backslash escaping in the script. A safe-path setting does not repair malformed script syntax, misspelling, a wrong directory, or a path that the operating system cannot resolve. Review both the entry’s syntax and the exact location of the file.
Use -safe 0 only for trusted playlist content
If you have confirmed that the failing input is an FFmpeg concat script and the diagnostic points to the safe-path restriction, -safe 0 is the relevant option to try. It disables that restriction for the concat demuxer and allows filenames beyond the portable set. Use it only when you trust the playlist and every path it names. It is not a general safety setting to add to an unknown playlist from an untrusted source.
For example, a minimal script for trusted local files could be:
ffconcat version 1.0
file 'गीत.mp4'
file 'अगला गीत.mp4'
The marker on the first line must match the documented form exactly and must not have a byte-order mark. The entries name the files to concatenate; quoting is useful for characters that need it. In this example, the files are assumed to be available where the script’s relative paths resolve.
A corresponding command is:
ffmpeg -f concat -safe 0 -i playlist.txt -c copy output.mp4
This is an illustration of option placement, not a universal command for every broadcast. Stream copy is appropriate only when the media streams and target container fit the workflow. If the files differ in their streams, codecs, or time bases, concat can still fail after it has opened them. The FFmpeg concat documentation lists matching requirements; a filename fix does not make incompatible media compatible.
Do not add -safe 0 to a direct -i 'भजन.mp4' command and expect it to solve a path-passing issue. Nor should you use it for an M3U playlist or an application-specific list unless you have verified that FFmpeg is actually invoking the concat demuxer. Where the problem is how a stream is sustained rather than how a file is opened, how to loop a YouTube study playlist without a gap between videos covers a different operational question.
Place the option before its matching -i
FFmpeg command-line options apply in relation to inputs and outputs. For concat, place -safe 0 with the concat input options and before the -i that names the script. This makes the relationship clear and ensures the setting is associated with the input it is meant to control.
Correct:
ffmpeg -f concat -safe 0 -i playlist.txt -c copy output.mp4
Here, -f concat selects the input demuxer, -safe 0 changes its path check, and -i playlist.txt supplies that input. The output option and output filename follow. If your command has multiple inputs, keep the option beside the relevant concat input rather than placing it after all inputs or after the output name.
This matters especially in longer commands used for a live channel. A command may read a logo, an audio bed, a concat script, and a YouTube output. An option positioned next to the wrong -i can affect a different input or have no effect on the one that is failing. If an application creates the command, check its supported input options and where it places them; do not assume a setting in a general preferences panel is applied to every input.
The invocation layer is also relevant for direct paths. On some systems, the shell interprets quotes and backslashes before FFmpeg sees them; a GUI application may instead construct arguments itself. Use the quoting rules for the shell or tool that runs the command, and avoid copying shell quotes literally into a configuration field unless that tool expects them. The official FFmpeg command-line reference is the right place to check the invocation syntax for the installed command-line tool.
Test the filename and read the full error
Before changing a working playlist, make a copy and test the exact entry that fails. Confirm that the filename and directory shown to FFmpeg match the real file, including spelling, extension, and any spaces. If the path is relative, check the working directory from which the command runs; a script launched by a scheduled task or service may start in a different directory from your terminal.
A useful first test is to open the media file directly with FFmpeg using the exact path, without the concat script. If that fails too, the cause may be path handoff, shell quoting, permissions, or the file itself rather than concat’s safe-path check. If direct opening works but the concat script reports an unsafe path, the distinction points towards the concat setting. Keep the test small and preserve the original files until the cause is clear.
Read the complete FFmpeg output, not only the last line shown by a streaming dashboard. An error about an unsafe name suggests a different issue from “No such file or directory”; an invalid-data message may mean the path opened but the content could not be probed. If the file opens and a later message concerns streams or codecs, the filename step may already be resolved.
If -safe 0 changes the error from a path rejection to a media or stream error, that is useful evidence: FFmpeg has progressed further, but there is another problem to address. Concat inputs are expected to match in stream layout, codecs, and time base for the documented workflow. Container support and codec support are also separate matters, as the FFmpeg FAQ explains. A file can be readable as a container while a particular stream remains unsuitable for the next stage.
Once the local test succeeds, rerun the stream with the same input and monitor the FFmpeg log long enough to confirm it proceeds beyond the formerly failing entry. If you change filenames or playlist paths, test those exact changes rather than relying on a successful run using a renamed copy. For a long-running channel, a repeatable local input test is more useful than repeatedly restarting YouTube while the underlying file still fails to open.
If maintaining a local computer for an always-on broadcast is itself the practical difficulty, that is a separate choice from this filename diagnosis. StreamNeo removes the need to keep your computer on for a file-based YouTube broadcast, but you still need to prepare the media and playlist correctly before the channel runs. For the operating trade-off, see how to run a 24/7 YouTube stream without keeping a laptop open in India.
Keep the fix scoped to the actual failure
A reliable repair starts with the narrowest change that matches the evidence. If the command opens a direct file and the path is wrong, correct the path or the way the application passes it. If a concat script rejects a trusted local path as unsafe, test -safe 0 before that script’s -i. If FFmpeg reaches the file and then reports a format or stream error, investigate the media rather than widening filename permissions.
It is worth keeping a note of the original command, the exact error, the playlist format, and the change that altered the result. That makes later maintenance easier when a playlist is edited or moved. It also prevents a temporary test setting from quietly becoming a universal default for playlists whose contents have not been checked.
For a channel that uses Hindi song titles, consider whether you can keep the names readable while also making the file paths predictable for the tools that consume them. Renaming every file is not required by the concat documentation, and it may make a collection harder for people to maintain. If you do use a simpler alias or directory, keep a clear mapping and update all playlist entries consistently; a mismatch between renamed media and the script merely replaces one path error with another.
The right conclusion is conditional: -safe 0 is a documented remedy for concat’s safe-path check when the playlist is trusted. It does not guarantee that every Devanagari filename, shell, operating system, codec, or streaming workflow will work. If the error remains ambiguous, capture the full command and diagnostic and compare them with the documentation for the installed FFmpeg version.

FAQ
Does FFmpeg categorically fail to read Devanagari filenames?
No. The concat documentation describes a safe-path rule for concat scripts; it does not establish a general inability to read Devanagari. Check the input type, exact path passed to FFmpeg, and full error before deciding which layer failed.
Should I add -safe 0 to any playlist command?
No. Use it only when you have confirmed that FFmpeg is reading a concat script and the safe-path check is the problem. The option is not a general fix for direct inputs or other playlist formats, and it should only be used with playlist content you trust.
Why does the command put -safe 0 before -i?
It is an input option for the concat demuxer, so place it before the -i that supplies the concat script. Keeping it alongside the matching input avoids confusing it with options for another input or the output.
What if the error changes after using the option?
A different error can mean FFmpeg has passed the path check and reached a later stage. Check whether it now reports a missing file, invalid media, or incompatible streams or codecs; each calls for a different fix.
