wickedlemon 6 Posted October 9, 2020 Share Posted October 9, 2020 Playing music files if transcoding is required I'm getting the following error: [flac @ 0x7f19d0] Invalid audio stream. Exactly one FLAC audio stream is required. Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument Here's an example ffmpeg command: /bin/ffmpeg -y -f ogg -i "/data/PI/Music/The Aquabats!/The Aquabats! 2011 Hi-Five Soup!/01 The Shark Fighter!.opus" -map 0:0 -vn -sn -c:a:0 copy -ar:a:0 48000 -ac:a:0 2 "/config/transcoding-temp/X86029F.flac" I just end up with a zero size file in the transcoding temp directory. If I remove flac as a direct stream codec from the profile to force transcoding it will transcode flac to flac with no problems and it creates a temp file ok. It just won't convert to a different codec. FLAC -> MP3 and OPUS - >MP3 also gave a similar error. I've tried running the ffmpeg command on my PC directly and get the same error. If I remove"-c:a:0 copy" from the string transcoding works ok. I'm not an expert with Ffmpeg, so does anyone know how I can fix this error in Emby? ffmpeg-transcode-9194e8e0-c1dd-48b4-9d6b-1c5cf970173f_1.txt Link to comment Share on other sites More sharing options...

Luke 37020 Posted January 6, 2021 Share Posted January 6, 2021 @wickedlemon it's trying to convert to flac because that's what you put in your transcodingprofiles. try replacing it with this: <TranscodingProfile container="mp3" type="Audio" audioCodec="mp3" estimateContentLength="false" enableMpegtsM2TsMode="false" transcodeSeekInfo="Auto" copyTimestamps="false" context="Streaming" minSegments="0" segmentLength="0" breakOnNonKeyFrames="false" /> That will set it back to the default of mp3 and then it should work.

Luke 37020 Posted March 7, 2021 Share Posted March 7, 2021 @wickedlemon with Emby Server 4.6 I would suggest removing your custom profile and letting the server detect the supported formats of the device. It should just work now. Thanks. Link to comment Share on other sites More sharing options...
