* | | Improve support for PGS subtitles.David Mitchell2012-01-232-81/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous implementation assumed that a new picture would always supersede the previous picture. Similarly, presentation segments were assumed to pertain to the most-recently-read picture. However, each presentation segment may refer to 0 or more pictures by their ID. Picture IDs may repeat, and a repeated picture ID indicates that the old picture for that ID is no longer needed and may be discarded. The new implementation allocates a buffer with one slot for each possible picture ID (the picture ID is a 16-bit field) and properly decodes presentation segments so that all relevant pictures are output upon encountering a display segment. Given that most PGS streams are unlikely to use more than a small fraction of the available picture IDs, it would probably be better to use a more memory-efficient data structure. I'm lazy though, so I leave this to a more motivated individual. I've tested the code with MKV files in VLC (a recent revision from their git repo) and with HandBrake (a version that I hacked up to use ffmpeg's PGS subtitle decoder).

| * | mxfdec: hybrid demuxing/seeking solutionJanne Grunau2012-01-223-193/+499
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This uses the old demuxing code for OP1a and separate demuxing code for OPAtom. Timestamp output is added to the old demuxing code. The seeking code is made to seek to the start of the desired EditUnit only, from which the normal demuxing code takes over (if OP1a). This means we do not use delta entries or slices, only StreamOffsets. OPAtom seeking basically works like before. This also makes D-10 seeking behave the same way as OP1a and OPAtom. In other words, we allow seeking before the start or past the end for D-10 too. Based on several patches by Tomas Härdin <tomas.hardin@codemill.se> and Reimar Döffinger <Reimar.Doeffinger@gmx.de>. Changed av_calloc to av_mallocz, added overflow checks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | It is a really bad idea to assign a video codec id when we have set codec_type to audio and vice versa. Prevents detection of mp2 in mxf as mpeg2video. Signed-off-by: Janne Grunau <janne-libav@jannau.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Specifically, this means parsing as before until we run into essence. At that point we seek to the footer and parse until EOF. After that we start seeking backward to the previous partition and parse that until we run into essence or the next partition. This procedure is repeated until we encounter the last partition we parsed in the forward direction. The end result of all this is that large essence containers are not needlessly parsed. This speeds up parsing large files a lot. Signed-off-by: Janne Grunau <janne-libav@jannau.net>

| * | avserver: fix build after the next bump.Anton Khirnov2012-01-222-11/+13
| | | | | | | | | | | | | | | | | | | | | Now that 0.8 is out we can reapply this commit. It breaks shared avserver builds due to avserver using internal libavformat symbols, which are now hidden, so this commit also disables avserver with --enable-shared.
