* 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/tscc: Don't free uninitialized z_streamAndreas Rheinhardt2021-05-10
| | | | | | | | It is not documented to be safe to call inflateEnd() on a z_stream that has not been successfully initialized via inflateInit(); so record whether it has been successfully initialized. 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().

* lavf/framecrcenc: do not hash side dataAnton Khirnov2021-05-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are no guarantees that all side data types have the same representation on all platforms. Tests that change output due to this: id3v2-priv-remux, cover-art-mp3-id3v2-remux, gapless-mp3: SKIP_SAMPLES, which is tested by fate-gapless-mp3-side-data matroska-vp8-alpha-remux: MATROSKA_BLOCKADDITIONAL, which is tested by remux itself (side data is written into output) matroska-mastering-display-metadata: MASTERING_DISPLAY_METADATA and CONTENT_LIGHT_LEVEL, which are tested by ffprobe invocation in the same test matroska-spherical-mono-remux: STEREO3D and SPHERICAL, which are tested by ffprobe invocation in the same test segment-mp4-to-ts: MPEGTS_STREAM_ID, which is tested by ts remuxing tests webm-webvtt-remux: WEBVTT_IDENTIFIER/SETTINGS, which is tested by the ffprobe invocation in the same test mxf-d10-user-comments: CPB_PROPERTIES, which is tested by mxf-probe-d10 mov-cover-image: SKIP_SAMPLES, which is tested for mov by mov-aac-2048-priming copy-trac3074: AUDIO_SERVICE_TYPE, which is tested by fate-hls-fmp4_ac3
* fate: drop the vp8-alpha testAnton Khirnov2021-05-09
| | | | It is redundant with matroska-vp8-alpha-remux.
* fate-run.sh: print stream side data in probeaudiostream()Anton Khirnov2021-05-09

* 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/avpacket: always initialize the new packet in avpriv_packet_list_put()James Almer2021-05-08
| | | | | | | If a copy callback is provided by the caller, the packet passed to it was zeroed instead of initialized with default values. Signed-off-by: James Almer <jamrial@gmail.com>
* avformat/matroskadec: remove special handling of av1c extradataJan Ekström2021-05-08
| | | | | Libavcodec can now handle the standard AV1CodecConfigurationRecord extradata as-is.
* avformat/mov: remove special handling of av1c extradataJan Ekström2021-05-08
| | | | | | Libavcodec can now handle the AV1CodecConfigurationRecord structure as-is when passed as extradata, so the standard behavior of read-box-into-extradata should suffice, just like with AVC and HEVC.
* 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>
