Luca Barbato	22141917a9	Revert "h264: Properly set coded_{width, height} when parsing H.264." This reverts commit `b47904d158`. coded_{width, height} overwrites width and height in avcodec_open and it currently just report the non-lowres size.	13 years ago

Michael Niedermayer	2fb9fc0f6c	h264: improve max slices error message Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Mans Rullgard	5cc2600964	dsputil: create 16/32-bit dctcoef versions of some functions High bitdepth H.264 needs 32-bit transform coefficients, whereas dnxhd does not. This creates a conflict with the templated functions operating on DCTELEM data. This patch adds a field allowing the caller to choose the element size in dsputil_init() and adds the required functions. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Mans Rullgard	add41decd9	Remove return statements following infinite loops without break These statements cannot be reached and are thus not needed. This removes a number of compiler warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Jason Garrett-Glaser	9a0dda8b3a	H.264: disable 2tap qpel with CODEC_FLAG2_FAST and >8-bit 2tap qpel isn't implemented yet for high bit depth, so it just breaks decoding.	14 years ago

Alexander Strange	3803af22d8	h264: Complexify frame num gap shortening code By observation it did not seem to handle prev_frame_num > frame_num. This does not affect any files I have. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Mike Scheutzow	aa15e68721	Fix decoding of mpegts streams with h264 video that does NOT have b frames One of the causes of this bug is that the h264 parser defaults low_delay to 1, but the h264 codec defaults low_delay to 0. Really Ugly. After many hours of looking at this, I'm still not sure how has_b_frames is intended to behave, but to me the implementation appears way more complicated than it ought to be. My patch relies on the encoder to set an optional field in the SPS. This works for libx264 streams, but I'm not sure that all h264 encoders will set it.

Jason Garrett-Glaser	c90b94424c	4:4:4 H.264 decoding support Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.	14 years ago

Michael Niedermayer	f0e9ee8d94	Revert "H264: Split out hl_motion and template it, this seems a bit faster" This reverts commit `a50f0bea25`.
