I am experiencing the same audio playback problem with XAVC-S from a Sony RX100 V digital camera.
I am a beginner, with very small experience with video editing/codecs, but I'm able to learn
I was previously able to read out the "Pcm s16 be (twos) codec" from VLC, but that was it for me...
For my own file the "ffmpeg -i C0001.mp4 -c:v copy -c:a pcm_s16le C0001-s16le.mkv" did the job for correct audio playback in Avidemux (windows 8, 64bit). It seems to play correct for the whole 27 minutes.
eumagga0x2a - thank you
I will look for the dosdan's solution in the future too (thanks again).
I am now able to cut the C0001-s16le.mkv file without loosing the audio; "copy" is still not supported, but a try with first chosen audio codec mp3 (lame) worked perfect.
I took the mp4v2 Muxer with default settings, hope this is correct for my XAVC-S files.
Could you please advise, give a recommendation, for good Audio-Codec option for my further reco(r)dings/ trims?
I will use my files for general Windows playback and I'm going to video-edit the files in the future, so I am looking for a tip for a good general purpose audio codec.
PS As we are speaking of temperatures: as I recorded my home trip last weekend, there was -14.5C in Poland. Now it's comfy +1C in Germany.
