[FFmpeg-user] AVI format for huge V210 content

[Roberto Cano]

Hi all,

I'm using a custom compiled version of ffmpeg 2.0.2 to filter an original
v210 movie with pcm_s24le audio track with 10 channels. The transcoding is
done to v210 at the output and I'm using a custom video filter to overlay
some letters.

I use the following command:

ffmpeg -i orig.avi -map0 -c copy -c:v v210 -vf custom=text=sample output
*.avi*


The original file is a 1:36:00 movie in v210 at 1920x1080, so really huge.
The output file has around 700GB (similar to the input). The thing is that
the output file lacks the audio track. What I see during the transcoding is
the following:

At least one output file must be specified


So no audio in it.


I see two things here:


 - AVI container complains about RIFF index. This is because every GB of
file the container need to add a RIFF index to the file, but this file is
huge and the maximum number of indices is 256, so after 256GB of file it
starts complaining. Could this affect the audio track?

 - Generated file is 700GB. Is this too big for ffmpeg to add the audio
track? Is the audio track added at the end, or interleaved?


If I generate small snippets, around 3.7GB each then the audio track is
there for the AVI files.


Thank you very much for the help.


Kind regards,
