Check the values of the ContentEncoding elements more strictly and don't use tracks for which it's invalid. Check that the track number is unique for this stream. Check that seek positions are below G_MAXINT64 as our seeks are int64-based and overflows will fail badly. After seeks also don't push SimpleBlocks until the first one containing a keyframe is found. Before this was done only for normal Blocks.

Not fully finished, but better than what we used to have and definately worth a first broad testing. I've revived rifflib. Rifflib used to be a bytestream-for-riff, which just dup'ed bytestream. I've rewritten rifflib to be a modern riff- chunk parser that uses bytestream fully, plus adds some extra functions so that riff file parsing becomes extremely easy. It also contains some small usability functions for strh/strf and metadata parsing. Note that it doesn't use the new tagging yet, that's a TODO. Avidemux has been rewritten to use this. I think we all agreed that avidemux was pretty much a big mess, which is because it used all sort of bytestream magic all around the place. It was just ugly. This is a lot nicer, very complete and safe. I think this is far more robust than what the old avidemux could ever have been. Of course, it might contain bugs, please let me know. EBML writing has also been implemented. This is useful for matroska. I'm intending to modify avidemux (with a riffwriter) similarly. Maybe I'll change wavparse/-enc too to use rifflib. Lastly, several plugins have been modified to use rifflib's fourcc parsing instead of their own. this puts fourcc parsing in one central place, which should make it a lot simpler to add new fourccs. We might want to move this to its own lib instead of rifflib. Enjoy!

Check the values of the ContentEncoding elements more strictly and don't use tracks for which it's invalid. Check that the track number is unique for this stream. Check that seek positions are below G_MAXINT64 as our seeks are int64-based and overflows will fail badly. After seeks also don't push SimpleBlocks until the first one containing a keyframe is found.

Check the values of the ContentEncoding elements more strictly and don't use tracks for which it's invalid. Check that the track number is unique for this stream. Check that seek positions are below G_MAXINT64 as our seeks are int64-based and overflows will fail badly. After seeks also don't push SimpleBlocks until the first one containing a keyframe is found. Before this was done only for normal Blocks. Update some FIXME/TODOs. * gst/matroska/ebml-read.c: (gst_ebml_read_peek_bytes), (gst_ebml_read_utf8), (gst_ebml_read_header): Improve debug output. * gst/matroska/matroska-ids.c: (gst_matroska_track_init_video_context): * gst/matroska/matroska-ids.h: * gst/matroska/matroska-mux.c: (gst_matroska_mux_video_pad_setcaps): Remove eye mode and don't parse it anymore. We can't use that information in GStreamer yet so it's useless.

Check the values of the ContentEncoding elements more strictly and don't use tracks for which it's invalid. Check that the track number is unique for this stream. Check that seek positions are below G_MAXINT64 as our seeks are int64-based and overflows will fail badly. After seeks also don't push SimpleBlocks until the first one containing a keyframe is found. Before this was done only for normal Blocks.

We can't use that information in GStreamer yet so it's useless.
