* avformat/demux: Add new demux.h headerAndreas Rheinhardt2022-05-10
| | | | | | And move those stuff already in demuxer-only files to it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat: Avoid allocation for AVStreamInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | Do this by allocating AVStream together with the data that is currently in AVStreamInternal; or rather: Put AVStream at the beginning of a new structure called FFStream (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVStreamInternal altogether.

* lavf: move AVStream.*index_entries* to AVStreamInternalAnton Khirnov2020-10-28
| | | | | | | Those are private fields, no reason to have them exposed in a public header. Since there are some (semi-)public fields located after these, even though this section is supposed to be private, keep some dummy padding there until the next major bump to preserve ABI compatibility.
* avformat/mlvdec: Only store dimensions after having validated themAndreas Rheinhardt2020-08-18
| | | | | | | Otherwise it might happen that invalid dimensions are used when reading a video packet; this might lead to undefined overflow. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat/mlvdec: Don't leak open AVIOContexts on errorAndreas Rheinhardt2020-08-18

* avformat/mlvdec: Check for existence of AVIOContext before using itAndreas Rheinhardt2020-08-18
| | | | | | | | | | | The mlv demuxer supports input split into multiple files; if invalid data is encountered when parsing one of the subsequent files, that file is closed. But at this point some index entries belonging to this file might already have been added. In this case, the read_packet function might try to use the AVIOContext (which is NULL) to read data which will of course crash. This commit fixes this.

* mlvdec: validate bits_per_coded_sampleAndreas Cadhalpun2015-12-22
| | | | | | | | | | | A negative bits_per_coded_sample doesn't make sense. If it is too large, the size calculation for av_get_packet overflows, resulting in allocation of a too small buffer.
