Public bug reported:
Consider the attached Ogg file, with Theora video and Vorbis audio,
produced with recordmydesktop. (The sound track is silent.)
The following command works, and produces the correct output--an Ogg
file containing only the Vorbis stream from the original input.
$ ffmpeg -i theora-vorbis-sample.ogg -vn -acodec copy out.ogg
However, the following produces the following, and the output doesn't
contain the video; ogginfo reports that the stream, which should be
Theora-only in an Ogg package, has "Warning: EOS not set on stream 1".
$ ffmpeg -i theora-vorbis-sample.ogg -an -vcodec copy out.ogg

The issue is not with the output container format; I get truncated AVI,
MOV and MKV files as well. It appears that ffmpeg is not copying the
Theora video correctly.
