* 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>

Also move alloc/init code from the write_header() functions to dedicated init() functions, and the cleanup code from the write_trailer() functions to dedicated deinit() functions. hash_free() and framehash_free() turn out to be identical here, but will differ in the subsequent commit, so they are not consolidated.

* avformat/utils: Preserve integrity of linked listAndreas Rheinhardt2019-09-181-4/+3
| | | | | | | | | | | | | | | | 1. Instead of relying on ff_packet_list_get to get the oldest element in an AVPacketList, ff_read_packet used its own ad-hoc code. Said code forgot to set the end of the list to NULL if the last element of the list has been removed, thereby leaving the list in an inconsistent state. 2. Furthermore, if the list was not empty, the oldest element of the list would always be copied into another packet structure before it was known whether the oldest entry of the list would be removed. This makes the ownership confusing and potentially copies unnecessarily. Both of these issues have been fixed. ff_packet_list_get is used now.

* avformat/internal: Improve documentation of ff_packet_list_getAndreas Rheinhardt2019-09-181-1/+4
| | | | | | | | | | | | | | | The documentation of ff_packet_list_get currently didn't match the actual usage: 1. It said that the destination packet is supposed to be initialized. But this makes no sense given that it will be overwritten completely and flacenc, mp3enc and ttaenc ignored this. 2. ff_packet_list_get returns an int, although it can't fail in case the packet list is not empty (for which there is an assert). Again, several callers didn't check for any return value. In both cases, the documentation has been adapted to match actual usage.
