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.
