5 months ago Also I cannot find how to record in qtrle with alpha.
When I add -c:v qtrle it says "unused"
Edit: Nevermind, using the long label for the qtrle codec works: add 1-1 FILE test.mov -codec:v qtrle, but they have the same issue I mention above when playing.

3 months ago I tried playing those files with version 2.0.7 and they play no problem.

1 month ago Problem seems to be a lack of ffmpeg parameters when creating the file. It plays fine when declaring the format option:
add 1 file test3.mp4 -format mpegts

Alternate group : 1Given that it's coming from a default state of ffmpeg format when you don't specify it, I'm not sure if it's a bug.
@Julusian feel free to close it if you think it's not a fixable bug on Caspar.
Edit: To fix the QTRLE files we have to specify some audio codec, for example -codec:a ac3_fixed or ac3, so it all seems to be related to the default audio codec being unable to set a proper channal layout or codec, hence Mediainfo displaying ?????????? on 'Channel Layout'.
The example that worked for me: add 1 FILE test_alfa.mov -codec:v qtrle -codec:a ac3_fixed

1 month ago Applying an audio filter for a set number of audio channels seems to fix the issue as well: -filter:a pan=2c|c0=c2|c1=c3

Alternate group : 1I tested mp4 and qtrle and both seem to play nicely with the following creation commands:
add 1-100 file test3.mp4 -filter:a pan=2c|c0=c2|c1=c3
add 1-100 FILE test_alfa.mov -codec:v qtrle -filter:a pan=2c|c0=c2|c1=c3
I do not know how well the audio is preserved after this. I have not tested audio retention/quality on the files.
Observed Behavior
I tried to record MP4 and MOV files, the recording works and is playable by VLC and Premiere 2024.
add 1 file test4.mp4However, Caspar can't play those same files.
Invalid channel layout 0seems to be the cause.Environment
