Fail to generate DVCPro50 in MOV #94

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
Command line as below.

What is the expected output? What do you see instead?
I expected to be able to write DVCPro50 media wrapped in QuickTime.  The error 
message suggests that ffmbc attempts to write the audio as aac instead of 
pcm_s16le, but, as seen below, not even adding "-strict experimental" seems to 
help.  (Or, possibly, the argument should have been added at some other 
position, but I'm not sure where - I've tried a few likely positions.)

What version of the product are you using? On what operating system?
FFmbc version 0.7-rc7
Ubuntu 10.04

Please provide any additional information below:

- Full commandline run (with -v 3) and everything the program printed
without
the repeating parts.

Oh, now I figured out where to put the argument, it's supposed to be:
ffmbc -v 3 -i elephants_dream_1080p24.y4m  -i ED-CM-5.1-DVD-C.flac  -i 
ED-CM-5.1-DVD-L.flac  -i ED-CM-5.1-DVD-R.flac  -i ED-CM-5.1-DVD-LS.flac  -i 
ED-CM-5.1-DVD-RS.flac  -i ED-CM-5.1-DVD-LFE.flac -r 29.97 -target dvcpro50 
DVCPro50_NTSC_4ch_16bit.mov -strict experimental -map_audio_channel 1:0:0:0:1:0 
-newaudio -map_audio_channel 2:0:0:0:2:0 -newaudio -map_audio_channel 
3:0:0:0:3:0 -newaudio -map_audio_channel 4:0:0:0:4:0

However, it seems I get different codecs in different audio channels in this 
way.  Note also that the audio tracks end up five seconds longer than the video 
(which has the expected length):

Repeat the audio codec before -newaudio, otherwise it will choose the format 
default which for .mov is aac. I should maybe change this behaviour.
About the length, the .flac file is just longer and shown in the Duration field
