How to automatically re-start FFmpeg if a stream shuts down ?

[Gwar]

hey guys,

I always record live streams with FFmpeg with the command ffmpeg -i "stream url" -c copy stream.ts

and wonderd if there is a way to automatically re-start the bat if the streams disconnects for a few seconds. Or if it is possible that the bat won't shut down when the stream disconnects and just pauses and continues after the stream is back on.
Does anyone have any idea how that would be possible ?

thanks guys
regards

Found this - does it work?

I haven't tested this but maybe:

:START
ffmpeg -y -i "stream url" -c copy stream.ts
if errorlevel 1 goto START

It won't pick up where it left off though.

Yes, it would overwrite the file and you lose everything except the last session. In the link I found they used >> but I haven't tested it.

Setting the truncate option to FALSE may keep it from overwriting.

ffmpeg -i "stream url" -c copy -truncate 0 stream.ts

Shure overwriting the file would be pretty bad. I tested that script but it won't even start the batch

I tried 7 different methods but that bat shuts down a half second after start

ffmpeg <URL> -t -c copy test.ts
ffmpeg <URL> -t -c copy test.ts
ffmpeg hls+<URL> -t -c copy test.ts
ffmpeg hls+<URL> -t 10 -c copy test.ts
ffmpeg <URL> -t 10 -c copy test.ts
ffmpeg <URL> -t 10 test.ts
ffmpeg <URL> -t test.ts

Maybe I'm not getting it and doing something wrong ?

ffmpeg -i "stream url" -c copy -truncate 0 stream.ts

thanks this one starts the batch. So I should use the scrip just as you wrote it or should I use it as

ffmpeg -i "stream url" -c copy -truncate false stream.ts ?

or does the zero mean "false" ?

thanks

Add "pause" on the line after ffmpeg... and see what error message you get.

the stream starts and I'm working with "ffmpeg -i "stream url" -c copy -truncate 0 stream.ts" I let you know if it records untl the end without shutdown thanks guys

Hi ,
Here below what I should do :

@echo on

:BEGIN
set ladate1=%date:~0,2%-%date:~3,2%-%date:~6,4%
if "%TIME:~0,1%"==" " (set ext=0%TIME:~1,1%H%time:~3,2%mn%time:~6,2%) else (set ext=%TIME:~0,2%H%time:~3,2%mn%time:~6,2%)

:START
ffmpeg -y -i "stream url" -c copy stream_%ladate1%_%ext%.ts
if errorlevel 1 goto BEGIN

pause
:fin

Cheers .

Or use youtube-dl instead of ffmpeg. It officially supports picking up where it left off.
