FFMPEG: how to get uncompressed audio in a MP4 file?

[marcorocchini]

Hi cats

please download this C0003.MXF

https://www.dropbox.com/s/eu2swbhni1q1oje/C0003.MXF?dl=0

I would like encode the c0003.mxf into a mp4 file with uncompressed PCM audio (48KHZ 16 bit) L+R with the CH1 and CH2 of the original mxf file

ffmpeg.exe -y -i v:\c0003.mxf -c:v libx264 -profile:v high422 -level:v 4.1 -g 33 -bf 0 -crf 18 -flags +ildct+ilme -top 1 -x264opts tff=1:colorprim=bt709:transfer=bt709:colormatrix=bt709 -filter_complex crop=out_h=1080:y=0,scale=interl=1:in_range=tv:out_range=tv -pix_fmt yuv422p -c:a pcm_s16le -ar 48000 -aspect 16:9 v:\out.mp4

but I get an error:



Could not write header for output file #0 (incorrect codec parameters ?)

please can anyone hel a cat? thanks

It's not possible with ffmpeg or open source software currently

You can use a MOV container and rename it MP4 and it will work ok for some applications
