Hello all,

I record TV shows using my freebox [1] and get .ts files as a result. They 
ends up taking a lot of space, and I'd like to regain part of it.

[1] http://en.wikipedia.org/wiki/Freebox

So I would like to split some files and remove commercials. I would also 
like to better compress them if possible.

The files may contain several soundtracks and subtitles. Sometimes, 
network failures cause the files to be slightly or more seriously broken.

My ideal (for now) workflow would be

1. detect file corruptions and warn me or fix them (automatically)
2. pre-detect commercials (automatically)
3. split shows, remove commercials (manually)
4. compress and convert to .mkv (automatically)

I would like the most of it to run in batch mode.

I don't really care to get Matroska files at the end, but the file format 
seems to be well fitted for this task.

Step 2 is optional but I would appreciate any mean to minimize the time 
spent on step 3. As commercials often cause changes in frames sizes and 
resolution, they might be easy to detect.

For step 3, I would try pitivi. I hope it won't loose the additional 
sountracks and subtitles.

For step 4., I would use gstreamer or handbrake. Maybe I should wait for 
them
to support WebM instead of H.264.

I guess step 1 is the tricky one. However, I think that if I don't check 
and fix the files on a systematic basis, I'll get indexes and sync 
troubles at the following steps.


So here are the questions :

- will pitivi and/or gstreamer handle the multiples soundtracks and
   subtitles ts files correctly?

- is step 1 necessary? Do you tool any tool that would do it?

- do you know any tool that would do step 2?

- would you suggest any change in the workflow?

Thanks a lot for any hint.

-- Sebastian
