I've got some code that outputs rawvideo to ffmpeg via pipe, which then overlays a png over it. If the code exits with an error, ffmpeg keeps going forever, I don't know how to stop it :( Any ideas? Here's an example:
set -o pipefail
(echo "error!!"; exit 1) | \
ffmpeg -f rawvideo -c:v rawvideo -s 1280x720 -pix_fmt bgra -i - \
-i my_icon.png \
-filter_complex "[0][1]overlay=50:50" \
out.mp4
Note ffmpeg DOES show an error message, but still does not stop, stuck in 'frame 0' forever, with a strange time attribute e.g. time:-577014:32:22.77:
[rawvideo # 0x563fc94427c0] Packet too small (8)

What is the reason of the error?
As explained in this answer
"file-level concatenation (-f concat) requires all files in the listing to have the exact same codec parameters. "
In this case, the input files have codecs opus and vorbis.
To resolve the issue, I recreated some files (silence files) so they all have the same CODEC as the files I am mixing them with.
In particular, instead of creating them using:
ffmpeg -f lavfi -i anullsrc=r=48000:cl=mono -t 5.8 -c:a libvorbis silence-5.8.ogg
I use now (note libopus)
ffmpeg -f lavfi -i anullsrc=r=48000:cl=mono -t 5.8 -c:a libopus silence-5.8.ogg
And the "concat with ffmpeg" works without any problem.
I also tried
ffmpeg -f lavfi -i anullsrc=r=48000:cl=mono -t 5.8 -c:a opus silence-5.8.ogg
But that returns with
[opus # 0x5607f1765900] The encoder 'opus' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
[opus # 0x5607f1765900] Alternatively use the non experimental encoder 'libopus'.
So, libopus works just fine (no need for opus)
I have an .srt subtitle file. I want to convert it into .ttml format(or xml) using ffmpeg command. I tried using traditional way to convert this. But ffmpeg throwing an error. Is there any way to convert this in Linux platform? Or any other command line applications do this conversion?
Below is the command I tried.
ffmpeg -i my_srt.srt -y srt-to-xml.xml -v verbose

I even tried like below.
ffmpeg -i my_srt.srt -y srt_to_ttml.ttml
It didn't work too.
It looks like ffmpeg 4.4 has minimal support for converting srt into ttml: font styles and positions are not preserved.
ttconv is an alternative.
The FFmpeg TTML muxer uses the .ttml extension:
ffmpeg -i input.srt output.ttml
The TTML encoder and muxer do not have any additional options as of writing this answer (see ffmpeg -h encoder=ttml & ffmpeg -h muxer=ttml).
I am running ubuntu 18.04(bionic) and i have generated a live RTP stream from kurento-media-server and i am converting it to HLS with this command of ffmpeg:
ffmpeg -protocol_whitelist file,udp,rtp -i rtp://127.0.0.1:55000 -vcodec libx264 -acodec libfdk_aac -f hls /live-stream/kurento-rtmp/hls/playlist.m3u8
However. it shows this output and doesn't do anything and stays there. Any ideas why this is happening are really appreciated.

I believe that at this stage ffmpeg is trying to determine the duration of input stream but since it is live it will never finish. If so, how would i flag ffmpeg that it is a live stream and not a local video.
I solved the issue by using -re flag which slows down ffmpeg to not read the whole stream at once and get frame by frame however, i should have passed sdp file instead of rtp uri because it gives this error:
[rtp # 0x55bee6277180] Unable to receive RTP payload type 96 without an SDP file describing it

The error was not with ffmpeg. The youtube-dl command was failing and resulting in the error.
Updated command
ffmpeg -f m4a $(youtube-dl -f bestaudio[ext=m4a] -g https://www.youtube.com/watch?v=qnjYyfkcaNI | sed "s/.*/-ss 0 -i &/") -to 60 -c copy -y /public/audio/test.m4a
Basically just had to remove the \'.
I also had to go one step further and give permission to the www-data apache group for the output folder since the command was being executed from a PHP script.
I am attempting to add audio to a MP4 file using ffmpeg at a specific time, eventually I also want the audio to only play until a certain point, so if you can help with that also that would be great, otherwise if you can just assist me in figuring out what is causing this error.
The arguments I use
-y "E:\Documents\Content Bar/Photo Booth\PhotosDrop\2018-05-15 14-01-16OUT.mp4" -itsoffset -i "E:\Downloads\wetransfer-250b26\05 Call of Love.mp3" -map 0:0 -map 1:0 -c:v copy -shortest "E:\Documents\Content Bar\Photo Booth\PhotosDrop\2018-05-15 14-01-16OUTOUT.mp4"
This results in the following error:

-i "E:\Documents\Content Bar/Photo Booth\PhotosDrop\2018-05-15 14-01-16OUT.mp4" -i "E:\Downloads\wetransfer-250b26\05 Call of Love.mp3" -filter_complex "[1]atrim=end=20,asetpts=PTS-STARTPTS[aud1];[aud1]adelay=6000|6000[aud];[0][aud]amix" -c:v copy out.mp4
