* http: Send a Range header even when the offset is 0Justin Ruggles2022-02-11
| | | | | | | Using Range allows for getting the full file size from the Content-Range header in the response, even if the server sends back the response using chunked Transfer-Encoding, which does not allow using Content-Length.
* http: Improve handling of Content-Range with Transfer-Encoding:chunkedJustin Ruggles2022-02-11
| | | | | | | When Transfer-Encoding:chunked is used, the client must ignore a Content-Length header, if present. However, it should not ignore a Content-Range header, which also includes the full size of the entity.

* avcodec/vp6: return value check for av_malloczJiasheng Jiang2022-02-11
| | | | | | | | | | | | As the potential failure of the av_mallocz(), the 's->alpha_context' could be NULL and be dereferenced later. Therefore, it should be better to check it and deal with it if fails in order to prevent memory leak, same as the av_frame_alloc() in ff_vp56_init().

* avformat/mpegts: initialize max_packet_size when sub-demuxerGyan Doshi2022-02-10
| | | | | | | | | | | bca30570d2 added a user option to set max_packet_size replacing a hardcoded value. This had a side-effect of leaving the field set to 0 when packet demuxing is carried out from another demuxer using avpriv functions, which could lead to demux failure. Hardcoded max_packet_size inside avpriv_mpegts_parse_open to 2048000 to avoid this. Value chosen to be 10x that of default value to accommodate large payloads.

* avcodec/pthread_frame: Properly unref frame in case of decoding failureAndreas Rheinhardt2022-02-09
| | | | | | | | | | Use ff_thread_release_buffer() instead of av_frame_unref(), as the former handles the case of non-thread-safe callbacks properly. (This is possible now that ff_thread_release_buffer() no longer requires a ThreadFrame.)

* avcodec/thread: Don't use ThreadFrame when unnecessaryAndreas Rheinhardt2022-02-09
| | | | | | | | | | | | | | | | | | | | | | | The majority of frame-threaded decoders (mainly the intra-only) need exactly one part of ThreadFrame: The AVFrame. They don't need the owners nor the progress, yet they had to use it because ff_thread_(get|release)_buffer() requires it. This commit changes this and makes these functions work with ordinary AVFrames; the decoders that need the extra fields for progress use ff_thread_(get|release)_ext_buffer() which work exactly as ff_thread_(get|release)_buffer() used to do. This also avoids some unnecessary allocations of progress AVBuffers, namely for H.264 and HEVC film grain frames: These frames are not used for synchronization and therefore don't need a ThreadFrame. Also move the ThreadFrame structure as well as ff_thread_ref_frame() to threadframe.h, the header for frame-threaded decoders with inter-frame dependencies.

| | | | | | | | | | This is in preparation for further commits that will stop using ThreadFrame for frame-threaded codecs that don't use ff_thread_(await|report)_progress(); the API for those codecs having inter-frame depdendencies will live in threadframe.h.

* avcodec/pthread_frame: Don't prematurily presume frame-threadingAndreas Rheinhardt2022-02-09
| | | | | | | | | | | Several of our decoders support both frame- as well as slice-threading; in case of the latter avctx->internal->thread_ctx points to a SliceThreadContext, not to a frame-thread PerThreadContext. So only treat avctx->internal->thread_ctx as the latter after having checked that frame-threading is active.
