* libavutil/hwcontext_opencl: Fix channel order in format support checkJarek Samic2019-04-09
| | | | | | | | | | | | | The `opencl_get_plane_format` function was incorrectly determining the value used to set the image channel order. This resulted in all RGB pixel formats being set to the `CL_RGBA` pixel format, regardless of whether or not they actually *were* RGBA. This patch fixes the issue by using the `offset` and depth of components rather than the loop index to determine the value of `order`.

* lavf/matroskaenc: Fix memory leak after write trailerJun Zhao2019-04-09
| | | | | | | | | | | | | | | | | | | Fix memory leak after write trailer for #7827, only store a audio packet whose buffer has size greater than zero in cur_audio_pkt. Audio packets with size zero, but with side-data currently lead to memleaks, in the Matroska muxer, because they are not properly freed: They are currently put into an AVPacket in the MatroskaMuxContext to ensure that the necessary audio is always available for a new cluster, but are only written and freed when their size is > 0. As the only use we have for such packets consists in updating the CodecPrivate it makes no sense to store these packets at all and this is how this commit solves the memleak.

* lavd/x11grab: fix vertical repositioningOctavio Alvarez2019-04-06
| | | | | | | | | | | | | | | | There is a calculation error in xcbgrab_reposition() that breaks vertical repositioning on follow_mouse. It made the bottom reposition occur when moving the mouse lower than N pixels after the capture bottom edge, instead of before. This commit fixes the calculation to match the documentation. follow_mouse: centered or number of pixels. The documentation says: When it is specified with "centered", the grabbing region follows the mouse pointer and keeps the pointer at the center of region; otherwise, the region follows only when the mouse pointer reaches within PIXELS (greater than zero) to the edge of region.

* avformat/matroskadec: Improve length checkAndreas Rheinhardt via ffmpeg-devel2019-04-05
| | | | | | | | | | | | | | | | | | | | | The earlier code had three flaws: 1. The case of an unknown-sized element inside a finite-sized element (which is against the specifications) was not caught. 2. The error message wasn't helpful: It compared the length of the child with the offset of the end of the parent and claimed that the first exceeds the latter, although that is not necessarily true. 3. Unknown-sized elements that are not parsed can't be skipped. Given that according to the Matroska specifications only the segment and the clusters can be of unknown-size, this is handled by not allowing any other units to have infinite size whereas the earlier code would seek back by 1 byte upon encountering an infinite-size element that ought to be skipped.

| | | | | | | | | | | | This brings the channel order in line with that used in 32-bit mode (BGR0). 24-bit decoding is disabled by default (#ifdef ZMBV_ENABLE_24BPP), and no prior encoders or sample videos are known to exist for this bit depth, so I consider this change in implementation is unlikely to affect anyone. The decision has been made in agreement with the DOSBox Development Team (dosbox.crew@gmail.com), specifically with harekiet, who wrote the original codec.
