[SOLVED] Bug Regression on Transcoding function (audio part with unknown channel layout)

Added by Dominique PLU almost 7 years ago

Hi

I have updated my install from a 4.1 to a fresh 4.3 GIT (Version: 4.3-846~g9538b1c (2017-12-22T22:22:27+0100))

I have reconfigured all, accounts, codecs profiles etc etc .. It works on all channels but on some channels, there is no more audio on stream or recording while using an audio recode whatever is codec used

Here is the log, you can see the message : "libav: TVHGraph: The filters 'in' and 'Parsed_anull_0' do not have a common format and automatic conversion is disabled." when the audio scheme is channels=? (unknow)

This problem occurs only with that kind of channels, all others (having good audio scheme) works well with transcode option

So if I record w/o transcoding, the stream is known as "?" but there is sound on file

Here is ffprobe of files with and w/o transoding

Something has change and I don't know what :) Having filter of audio stream or not change nothing to the result, the only way to have transcoding of audio is the audio channel layout correct.

Any help is welcome. Thanks in advance
