I am looking for a patch so that when using the below Channel layout flags, the FC comes out flagged as 'Center', not Mono, and also the DL and DR comes out as 'Left Total' 'Right Total'. Currently these 3 are coming out as 'Mono'. Is there a patch / command / flag to get these flagged correctly please?
The result currently comes out as:
Video
Front Left
Front Right
Mono (should be Center)
Left Surround
Right Surround
Mono (should be Left Total)
Mono (shold be Right Total)
Here is the command:
ffmpeg -i /Volumes/GRAID/EXPORTS/DESCRETE_TEST.mov -ss 45 -to 50 -filter_complex \
"[0:1]pan=FL|c0=c0[FL]; \
[0:1]pan=FR|c0=c1[FR]; \
[0:1]pan=FC|c0=c2[FC]; \
[0:1]pan=LFE|c0=c3[LFE]; \
[0:1]pan=BL|c0=c4[BL]; \
[0:1]pan=BR|c0=c5[BR]; \
[0:1]pan=DL|c0=c6[DL]; \
[0:1]pan=DR|c0=c7[DR]" \
-map v:0 \
-map "[FL]" \
-map "[FR]" \
-map "[FC]" \
-map "[LFE]" \
-map "[BL]" \
-map "[BR]" \
-map "[DL]" \
-map "[DR]" \
-vcodec prores -profile:v 3 -vtag apcn -f mov -y -c:a pcm_s24le /Volumes/GRAID/EXPORTS/DONE_TEST.mov
Below is the ffmpeg output from that.
ffmpeg -i /Volumes/GRAID/EXPORTS/DESCRETE_TEST.mov -ss 45 -to 50 -filter_complex \
