| | | | | | Initializing a VLC entails implicit allocations which may fail. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | ff_wma_init() can fail without freeing everything it has allocated; so add the FF_CODEC_CAP_INIT_CLEANUP to the codecs using it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/dnxhdenc: Fix segfault when using too many slice threadsAndreas Rheinhardt2021-05-10
| | | | | | | | | | | | | | The DNXHD encoder's context contains an array of 32 pointers to DNXHDEncContexts used in case of slice threading; when trying to use more than 32 threads with slice threading, the encoder's init function errors out, but the close function takes avctx->thread_count at face value and tries to free inexistent elements of the array, leading to potential crashes. Fix this by modifying the check used to decide whether the slice contexts should be freed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/wmaprodec: Make decoders init-threadsafeAndreas Rheinhardt2021-05-10
| | | | | | | | | | | | | In this case this actually fixes a potential data race: The static VLC tables were reinitialized every time an AVCodecContext has been initialized; while the mutex in avcodec_open2() ensured that the VLCs could not be initialized concurrently by multiple threads, nothing guaranteed that these VLCs are not read concurrently (when decoding a packet with an already initialized AVCodecContext) while another thread initializes them. This is undefined behaviour despite the values being written coinciding with the earlier values. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/vp9: Inline function with only one caller into itAndreas Rheinhardt2021-05-10
| | | | | | | | | The split into vp9_decode_init() and init_frames() is a remnant of using init_thread_copy() for frame-threading; the latter has been removed, so there is no reason for init_frames() not be part of vp9_decode_init().

* avcodec/avpacket: use av_malloc() to allocate an AVPacketJames Almer2021-05-08
| | | | | | | | av_mallocz() is superfluous as get_packet_defaults() is called immediately after it's allocated, which will initialize the entire struct to default values. Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec/h263, h263data: Move ff_h263_init_rl_inter to h263.cAndreas Rheinhardt2021-05-07
| | | | | | | | | | | | The SVQ1 decoder does not need mpegvideo or rl.c, but it uses stuff from h263data.c. But since 61fe481586425a41d45e371de1e875b49882477d h263data.c called ff_rl_init() and this of course led to build errors when the SVQ1 decoder is enabled and mpegvideo disabled. Fix this by moving ff_h263_init_rl_inter() to h263.c. Fixes ticket #9224. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | | | | | Here the packet size is known before allocating the packet because the encoder provides said information (and works with internal buffers itself), so one use this information to avoid the implicit use of another intermediate buffer for the packet data; and by switching to ff_get_encode_buffer() one can also allow user-supplied buffers.
