Andreas Rheinhardt	43991dbd05	avformat/assenc: Fix potential NULL + 1 Incrementing a NULL pointer is undefined behaviour, yet this is what would happen in case trailer were NULL before the check. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago

Haihao Xiang	bcdea21675	lavfi/qsvvpp: postpone vpp session initialization So there is a chance to update vpp parameters per frame Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>	1 year ago
Haihao Xiang	cf21ca9efb	lavfi/qsvvpp: store a copy of the sequence parameters We will postpone the vpp session initialization to when input and output frames are ready, this copy of the sequence parameters will be used to initialize vpp session.

Haihao Xiang	579711c2cc	lavfi/qsvvpp: check the parameters before initializing vpp session According to the description about MFXVideoVPP_Query [1], we may call MFXVideoVPP_Query to check the validity of the parameters for vpp session, use the corrected values to initialize the session.

Haihao Xiang	07139b6deb	lavfi/qsvvpp: track the runtime version in vpp context We may check whether a feature is supported via the runtime version in future. Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>	1 year ago
Yeoh, Hoong Tee	da4b2549c6	lavf/rtpenc_jpeg: Retrieve sampling factor from SOF0 In ff_rtp_send_jpeg, the type is defined based on PIX_FMT and color-range parsed in. There is limitation on current design where need to include support newly introduced PIX_FMT such as AV_PIX_FMT_QSV and there might be more and more in future. Hence, retrive the sampling factor from SOF0 in JPEG compressed header directly. This introduces flexibility to handle different type of new codec introduced in future.

Anton Khirnov	1617d1a752	fftools/ffmpeg: pass subtitle decoder dimensions to sub2video Restores behavior from before `20cacfe493`. Eventually this should be handled similarly to audio/video - with a filtergraph reset or a manual scaler.	1 year ago
Anton Khirnov	88f80977eb	fftools/ffmpeg: use AVFrame to pass subtitles from decoders to filters Allows to use the same buffering code for all media types. Will also be important for the following commit.	1 year ago
Anton Khirnov	fa717baaa5	fftools/ffmpeg_enc: constify the subtitle passed to enc_subtitle()	1 year ago
Anton Khirnov	e89a6d1089	fftools/ffmpeg_dec: move InputStream.prev_sub to Decoder It does not need to be visible outside of decoding code.	1 year ago
Anton Khirnov	a45b9d35b9	fftools/ffmpeg: move fix_sub_duration_heartbeat() to ffmpeg_dec This way ffmpeg.c does not need to access InputStream.prev_sub and it can be made private.	1 year ago
Anton Khirnov	01897c1788	fftools/ffmpeg_dec: move decoding to a separate thread This is only a preparatory step to a fully threaded architecture and does not yet make decoding truly parallel - the main thread will currently submit a packet and wait until it has been fully processed by the decoding thread before moving on. Decoder behavior as observed by the rest of the program should remain unchanged. That will change in future commits after encoders and filters are moved to threads and a thread-aware scheduler is added.	1 year ago
