Anton Khirnov	077b559433	hevc: handle a NULL sps in set_sps() properly This can happen in update_thread_context(), when the previous frame was corrupted.	9 years ago
Anton Khirnov	18156b53f9	hevc: do not pass an entire HEVCContext into export_stream_params() It only needs the parameter sets.	9 years ago
Anton Khirnov	650060dfb6	hevc_parser: parse and export some stream parameters Particularly those that will be needed by the QSV decoder. More can be added later as necessary.	9 years ago
Anton Khirnov	7f78155dc6	hevc: improve a comment That loop does the actual full decoding, so 'parse' can be misleading.	9 years ago
Anton Khirnov	d82e1adc20	hevc: move splitting the packet into NALUs into a separate function This function is independent of the decoding context, so we'll be able to use it in the parser.	9 years ago
Anton Khirnov	ae05b48655	hevc: eliminate the second call to hls_nal_unit() Also, make hls_nal_unit() work only on the provided NAL unit, without requiring a whole decoding context. This will allow splitting this code for reuse by the parser.	9 years ago
Anton Khirnov	d7bebe4805	hevc: skip invalid/ignored NALUs when splitting the packet There is no need to wait until actually decoding the NALU. This will allow to get rid of the second hls_nal_unit() call later.	9 years ago
Anton Khirnov	b11acd5732	hevc: remove HEVCContext usage from hevc_ps Factor out the parameter sets into a separate struct and use it instead. This will allow us to reuse this code in the parser.	9 years ago
Anton Khirnov	ab05ed4c32	mpegvideo_parser: export pixel format and dimensions	9 years ago
Andreas Cadhalpun	9f4c7397a2	hevc: check slice address length It is used as get_bits argument and reading 0 bits doesn't make sense. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Anton Khirnov	86eee85dad	bytestream2: set the reader to the end when reading more than available This prevents possible infinite loops with the calling code along the lines of while (bytestream2_get_bytes_left()) { ... }, where the reader does not advance. CC: libav-stable@libav.org	9 years ago
Luca Barbato	355864ef7a	g726: Do not crash on user mistake Properly report the sample rate as invalid CC: libav-stable@libav.org	9 years ago
Andreas Cadhalpun	1410eeb6ea	imc: Use correct position for flcoeffs2 calculation flcoeffs2[pos] should be the log2 of flcoeffs1[pos]. flcoeffs1[0] can be 0 here, thus flcoeffs2[pos] gets set to -inf, causing problems further down. This seems to have been copied from imc_decode_level_coefficients in commit `4eb4bb3` without updating the position.

Anton Khirnov	69ab9f53f9	hevc: split bitstream unescaping to a separate file It will be useful in the QSV HEVC encoder.	9 years ago
Anton Khirnov	fd124d8357	hevc_ps: split the code for parsing the SPS and exporting it into the context This will be useful in the later commits, where we want to parse an SPS without having a whole decoding context.	9 years ago
Vittorio Giovara	1761ab838c	lavc: Deprecate avctx.rc_strategy Only used by libxvid in ratecontrol module, so move it to a codec private option. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Stian Selnes	02b7c63087	h261: Signal freeze picture release for intra frames Freeze picture release should be set to 1 when we're responding to a fast update request. For simplicity we set it for all intra frames, including those that starts a GOP. Fixes issue where Tandberg MXP1700 does not recover from packet loss state since it's waiting for the freeze picture relase indication.

Stian Selnes	dc1de0b958	h261: Set 'still image mode off' in picture header Ref H.261 recommendation section 4.2.1.3, setting the still image flag to 1 disables still image mode. Some decoders require this in order to decode the bitstream as normal video. Fixes H.261 calls to Cisco E20. Also, reserved (aka spare) bits should be set to 1 unless specified otherwise.
