Anton Khirnov	598ce4ab4f	h264: call av_frame_unref() instead of avcodec_get_frame_defaults(). This is a temporary workaround to allow deprecating avcodec_get_frame_defaults(). The proper solution will be using a properly allocated AVFrame in Picture.	11 years ago
Vittorio Giovara	5b10ef729f	h264: parse frame packing arrangement SEI messages and save relevant stereo3d information	11 years ago
Anton Khirnov	f0259a587e	h264: check buffer size before accessing it Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	a553c6a347	lavc: use buf[0] instead of data[0] in checks whether a frame is allocated data[0] may be NULL for valid frames with hwaccel pixel formats.	11 years ago
Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Anton Khirnov	9eda9d3322	h264: free the tables and uninitialize the context on flush Prevents referencing empty frames when the first packet after the flush does not contain a frame.	11 years ago
Luca Barbato	08303d7741	hwaccel: Simplify ff_find_hwaccel It is always called by passing fields from an AVCodecContext.	11 years ago
John Stebbins	28096e0a80	h264: wait for initial complete frame before outputing frames This can be optionally disabled whith the "output_corrupt" flags option. When in "output_corrupt" mode, incomplete frames are signalled through AVFrame.flags FRAME_FLAG_INCOMPLETE_FRAME. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Rainer Hochecker	71cabb521a	h264: do not discard NAL_SEI when skipping frames Setting AVDISCARD_NONREF (e.g. after flushing) resulted in 100% dropped frames. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Ronald S. Bultje	c443117f25	dsputil: Remove dct_bits dct_bits is never set except in h264, where it is never used, thus remove it. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	5e83d9aced	h264: fully support cropping. Based on a patch by Vittorio Giovara <vittorio.giovara@gmail.com> Fixes Bug 378.	12 years ago
Ronald S. Bultje	85deb51a01	h264: Only initialize dsputil if error resilience is enabled It is only used for error resilience. This allows building the h264 decoder without dsputil, if error resilience is disabled. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	62844c3fd6	h264: Integrate clear_blocks calls with IDCT The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700 to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb (in the decode_slice loop) goes from 1759 to 1733 cycles on the clip tested (cathedral), i.e. almost 30 cycles per mb faster.

Martin Storsjö	e8cafd2773	h264: Clear the mb members via memset instead of using dsputil Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Janne Grunau	05fa79b844	hwaccel: fix use with frame based multithreading Allows use of AVHWAccel based decoders with frame based multithreading. The decoders will be forced into an non-concurrent mode by delaying ff_thread_finish_setup() calls after decoding of the current frame is finished. This wastes memory by unnecessarily using multiple threads and thus copies of the decoder context but allows seamless switching between hardware accelerated and frame threaded software decoding when the hardware decoder does not support the stream.	12 years ago
Ronald S. Bultje	0b499c9b06	h264: Make it possible to compile without error_resilience Error resilience is enabled by the h264 decoder, unless explicitly disabled. --disable-everything --enable-decoder=h264 will produce a h264 decoder with error resilience enabled, while --disable-everything --enable-decoder=h264 --disable-error-resilience will produce a h264 decoder with error resilience disabled.

Anton Khirnov	48d0fd2d62	h264: merge common_init() into ff_h264_decode_init. There is no point in keeping those separate.	12 years ago
Anton Khirnov	25408b2a06	h264: make ff_h264_frame_start static. It is not called from outside h264.c	12 years ago
Janne Grunau	a157c7f2b8	h264: fix bit depth changes with frame threading AVCodecContext.bits_per_raw_sample is updated from the previous thread in the generic update function before the codec specific update_thread function is called. The check for reinitialization of dsp functions uses bits_per_raw_sample. When called from update_thread_context it will be already at the current value and the dsp functions aren't updated if only the bit depth changes.	12 years ago
Hendrik Leppkes	9c9ede44f3	h264: allocate hwaccel privdata after the frame buffer This ensures the hwaccel privdata does not leak when a frame buffer could not be allocated (and toggle the assert when the frame is re-used). Having no frame buffer available is quite common when using the DXVA2 hwaccel in situations where the DXVA2 renderer is being re-allocated, for example when moving between displays.
