* lavf: Reset the entry count and allocation size variables on av_reallocp ↵Martin Storsjö2013-09-26
| | | | | | | | | | | | | | failures When av_reallocp fails, the associated variables that keep track of the number of elements in the array (and in some cases, the separate number of allocated elements) need to be reset. Not all of these might technically be needed, but it's better to reset them if in doubt, to make sure variables don't end up conflicting. Signed-off-by: Martin Storsjö <martin@martin.st>

* mov: Don't use a negative duration for setting other fieldsMartin Storsjö2013-09-17
| | | | | | | | | | Some files have the duration set to -1 in the mdhd atom, more or less legitimately. (We produce such files ourselves, for the initial duration in fragmented mp4 files.)

* mov: Do not allow updating the time scale after it has been setMartin Storsjö2013-07-15
| | | | | | | | | | | | The time scale is set in mdhd, and later validated in the enclosing trak atom once all of its children have been parsed. A loose mdhd atom outside of a trak atom could update the time scale of the last stream without any validation.

* mov: handle h263 and flv1 for codec_tag 'H','2','6','3'Janne Grunau2012-12-19
| | | | | | | | | | The sample in https://bugzilla.libav.org/show_bug.cgi?id=393 and samples/F4V/H263_NM_f.mp4 both have codec_tag H263 for different codecs. H263 is apparently used by Flash Media Server for Sorensen Spark videos. Patch based on commit 5442083b1c541dd166b3adf39131259fc846a62b by Carl Eugen Hoyos. Fixes bug 393.
* mov: validate number of DataReferenceBox entries against box sizeJanne Grunau2012-12-07
| | | | | Avoids a 2G memory allocation and parsing of random data in mov_read_dref(). The fuzzed sample sample.mp4_s224424 triggers this.
* mov: compute avg_frame_rate only if duration is knownJanne Grunau2012-12-07

| | | | Also reorder some other #include when applicable.
* mov: support random access point groupingYusuke Nakamura2012-09-19
| | | | | | | | | Frames described by this grouping are the starter of a closed or an open GOP. This is useful for open GOP of H.264 stream which is not described by sync sample atom. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* mov: check for EOF in long lasting loopsLuca Barbato2012-09-18
| | | | | | | A quite widespread pattern in the demuxer is read a 32bit unsigned integer and then loop till this value is reached. Checking for EOF prevents pathological situations.

* lavf: deprecate r_frame_rate.Anton Khirnov2012-07-29
| | | | | | | | | | | | | | | | | | | | According to its description, it is supposed to be the LCM of all the frame durations. The usability of such a thing is vanishingly small, especially since we cannot determine it with any amount of reliability. Therefore get rid of it after the next bump. Replace it with the average framerate where it makes sense. FATE results for the wtv and xmv demux tests change. In the wtv case this is caused by the file being corrupted (or possibly badly cut) and containing invalid timestamps. This results in lavf estimating the framerate wrong and making up wrong frame durations. In the xmv case the file contains pts jumps, so again the estimated framerate is far from anything sane and lavf again makes up different frame durations. In some other tests lavf starts making up frame durations from different frame.
