* 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.
