[FFmpeg-devel] [PATCH v3] avformat/dvd: new dvd:// protocol for reading dvd folder/images

Thanks for the patch. The reason there was no DVD support in ffmpeg
until now is that it is not as straightforward as it seems.

Your patch is missing documentation, including documentation about its
limitations. Please clarify various points:

- VOBs contain not only the movie but also menu data: will it be mixed
  along with the movie or skipped?

- Are the timestamps monotonous over a whole title?

- Does ffmpeg correctly detect all the subtitles streams?

- Does ffmpeg correctly detect the language of audio and subtitles
  streams?

- Are chapters detected?

Regards,
