[Bug 228569] Re: Please backports libtheora 1.0~beta3-1

[Fabio Pedretti]

I installed libtheora 1.0 beta3 compiled from source and, after running
ldconfig and assuring that the applications linked to the new libtheora
with ldd, I tested:

- vlc
  * played variuos ogg files, created with the ubuntu and 1.0-beta3 libtheora: no problem detected;

- ffmpeg2theora
  * encoded some file (some also from an .ogg source to test both new en/decoder): no problem detected;
  * produced files are of the same size with ubuntu library;
  * encoding speed is the same of the old library (+-1%);

- theora_dump_video
  * using the version in libtheora-bin (btw, this package is generated from the libtheora);
  * tried dumping (decoding) some same file using theora_dump_video: 1.0 beta3 is about 9-11% faster than with original version;
  * I also tested the md5sum of decoded files, with the 4 combination of
   - file encoded with ubuntu libtheora, decoded with ubuntu libtheora
   - file encoded with ubuntu libtheora, decoded with 1.0-beta3 libtheora
   - file encoded with 1.0-beta3 libtheora, decoded with ubuntu libtheora
   - file encoded with 1.0-beta3 libtheora, decoded with 1.0-beta3 libtheora
   with:
    theora_dump_video somevideo_encoded_with_ubuntu_libtheora.ogg | md5sum
    theora_dump_video somevideo_encoded_with_1.0-beta3_libtheora.ogg | md5sum
   and the md5sums are always the same.
