* avformat/utils: Fix memleaksAndreas Rheinhardt2019-09-251-4/+12
| | | | | | | | | | | | | | ff_read_packet had potential memleaks: 1. If av_packet_make_refcounted fails, it means that the packet is not refcounted, but it could nevertheless carry side data and therefore needs to be unreferenced. 2. If putting a packet on a packet list fails, it wasn't unreferenced. Furthermore, read_frame_internal leaked a packet's (side) data if a context update was required and failed.

* avformat/utils: Assert that stream_index is validAndreas Rheinhardt2019-09-251-4/+2
| | | | | | | | | | | There is currently an ordinary check for this (which would lead to a memleak), but given that no demuxer should ever return a packet with an invalid stream_index it is more appropriate for this to be an assert. FATE passes with this change. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>

| | | | | | This reverts commit eb5d0f18ff609ba2280cea4e2c6286d216c8756b. Together with 89f464e9, it breaks decoding of tiff files like fate-suite/exif/image_small.tiff

* avcodec/cbs_h264: Automatically free SEI payload on errorAndreas Rheinhardt2019-09-242-6/+15
| | | | | | | | | | | | | If adding an SEI message to an access unit fails, said SEI message was not touched, so that the caller had to free any data associated with it that might need to be freed. But given that ff_cbs_h264_add_sei_message can simply call cbs_h264_free_sei_payload, one can easily free the content of the SEI payload. This fixes a memleak when inserting a user data unregistered string for h264_metadata fails. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
