After fixing AV_PKT_DATA_SKIP_SAMPLES for reading vorbis packets from ogg, the actual decoded samples become fewer. Three fate tests are failing: fate-vorbis-20: The samples in 6.ogg are not frame aligned. 6.pcm file was generated by ffmpeg before the fix. After the fix, the decoded pcm file does not match anymore. Ideally the ref file 6.pcm should be updated but it is probably not worth it including another copy of the same file, only smaller. SIZE_TOLERANCE is added for this test case. fate-webm-dash-chapters: The original vorbis_chapter_extension_demo.ogg is transmuxed to dash-webm. The ref file webm-dash-chapters needs to be updated. fate-vorbis-encode: This exposes another bug in the vorbis encoder that initial_padding is not correctly set. It is fixed in the previous patch.
