[HELP] Trouble reading Pointer file in MXF type file
#19
Used aac as audio and don't get sound here too, which is why I asked whether the audio was silent or not. Wink
-> Since it sounds like there should be sound I'll look into it some more before I look more into opening such content with Avisynth, Vapoursynth and MPlayer.

Call I use atm. and that returns a silent output is:
ffmpeg -y -enable_drefs 1 -use_absolute_path 1 -i "C:\Users\Selur\Desktop\camb_730_Mackay2_2002(1).vmf\camb_730_Mackay2_2002(1).mov" -map 0:1 -vn -sn -ac 4 -ar 48000 -filter_complex "[0:1][0:2][0:3][0:4] amerge=inputs=4" -channel_layout 4.0 -acodec pcm_s16le -f wav "H:\Output\iId_1_aid_0_lang_en_07_34_19_871000.wav"
For testing I open a command prompt in Windows, navigate to the folder where the input lies and then call ffmpeg:
g:\Hybrid\ffmpeg.exe -y -enable_drefs 1 -use_absolute_path 1 -i "C:\Users\Selur\Desktop\camb_730_Mackay2_2002(1).vmf\camb_730_Mackay2_2002(1).mov" -map 0:1 -vn -sn -ac 4 -ar 48000 -filter_complex "[0:1][0:2][0:3][0:4] amerge=inputs=4" -channel_layout 4.0 -acodec pcm_s16le -f wav "H:\Output\test.wav"
This way the working directory is the current folder and ffmpeg finds the files. No clue why the output is silent so far. Sad

Quote:Just reading that PCM audio (which is the 4 streams) is raw format audio and that vlc for example doesn't recognise the formatting.
Real raw PCM does not come with headers so that is probably not a mistake in itself.
Quote:Unfortunately I cannot download my own file to check in FCPX as I don't have the bandwidth at home. Other similar files I have play the audio fine in FCPX.
Please report back once you could check the source you gave me in FCPX to be sure there really is audio to find. Wink
