Unable to decode "file.mp4" #1412

Closed yasn0st closed 3 years ago

yasn0st commented 3 years ago

All day I have been trying to get liquidsoap to play a video file. And I can't do it. I keep getting the message Unable to decode. I tried it in windows, tried it in ubuntu, compiled the application in opam. Replaced gavl with ffmpeg. Converted mp4 to xvid avi and ogv. And all to no avail.

I want to make a script that makes a video broadcast with music on youtube. Everything works with a static picture. But the video doesn't work.

script:

set("log.stdout",true)
set("log.file",true)

set("video.converter.preferred","ffmpeg")
set("decoder.file_extensions.ffmpeg",["mp3","mp4","m4a","wav","flac","ogg","wma","webm","osb"])

set("frame.video.width",1280)
set("frame.video.height",720)
set("frame.video.samplerate", 25)

video = mksafe(single("./vid/img2_1.mp4"))
s = mksafe(playlist("./mp3"))
source = mux_video(video=video,s)
output.youtube.live.ffmpeg(id="youtube",fallible=true,bitrate="500",key="***",source)

The problem here comes from the fact that you are trying to decode the file with video only as indicated by

{audio=0;video=1;midi=0}

whereas it has audio. You should add

video=drop_audio(video)

to decode with audio and drop it. This should work on 2.0 though where we can drop audio if necessary.
