* mxfdec: fix NULL checking in mxf_get_sorted_table_segments()Xi Wang2013-01-04
| | | | | | | | | | | | The following out-of-memory check is broken. *sorted_segments = av_mallocz(...); if (!sorted_segments) { ... } The correct NULL check should use *sorted_segments. Signed-off-by: Xi Wang <xi.wang@gmail.com> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* mxfdec: let pkt->pts = mxf->current_edit_unit if intra-onlyTomas Härdin2012-07-10

* mxfdec: fix Avid AirSpeed files being misinterpreted as OP1aTomas Härdin2012-07-10
| | | | | | | | | The "ECs != 1 -> OP1a" assumption was wrong. Luckily, the file that triggered that behavior had two ECs, not zero. Hence distinguishing between them is simple in this case. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* mxfdec: truncate packets that extend past the next edit unitTomas Härdin2012-07-10

* mxfdec: set pixel format for cdci picture formatsPhilip de Nier2012-07-10
| | | | | | | | | | | | | | | | | | The properties of the CDCI Descriptor are insufficient to specify the pixel format for uncompressed picture data. SMPTE 377-1 and RP224v10 have defined a set of picture coding labels to indicate what formatting was used. This patch uses 2 labels to detect UYVY422 or YUYV422 pixel formats. It defaults to UYVY422 for 8-bit 4:2:2 pictures to support files that were created before the coding labels were introduced ~2008 The codec pix_fmt default was changed from 0 (PIX_FMT_YUV420P) to -1 (PIX_FMT_NONE) Reviewed-by: Baptiste Coudurier <baptiste.coudurier@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | This supports detection of uncompressed picture in files that didn't include a Picture Coding Label.

* mxfdec: replace x>>av_log2(sizeof(..)) by x/sizeof(..).Ronald S. Bultje2012-07-07
| | | | | | Also replace x>>av_log2(sizeof(..)) + 1 by x/sizeof(..). The +1 is probably meant to emulate av_log2_ceil(sizeof(..)) in cases where ".." is not a power of two.
* mxfdec: Ignore the last entry in Avid's index table segmentsTomas Härdin2012-02-09
| | | | | | | | The last entry is the total size of the essence container. Previously a TemporalOffset error would be logged, even though segments like these are expected. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* mxfdec: Sanity-check SampleRateTomas Härdin2012-02-09

* mxfdec: Handle small EditUnitByteCountTomas Härdin2012-02-09
| | | | | | | These are common with audio atoms. Without this the demuxer would read two bytes at a time for a mono 16-bit file. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* mxfdec: Never seek back in local sets and KLVsTomas Härdin2012-02-09
| | | | | | | | | Specially crafted files can lead the parsing code to take too long. We fix a lot of these problems by not allowing local tags to extend past the end of the set and not allowing other KLVs to be read past the end of themselves. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* mxfdec: Move the current_partition check inside mxf_read_header()Tomas Härdin2012-02-09

* mxfdec: Fix infinite loop in mxf_packet_timestamps()Tomas Härdin2012-02-09

* mxfdec: Do not parse slices or DeltaEntryArrays.Tomas Härdin2012-01-22
| | | | The most recent demuxing/seeking code does not need them.
* mxfdec: hybrid demuxing/seeking solutionJanne Grunau2012-01-22
| | | | | | | | | | | | | | | | | | 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>
