Anton Khirnov	527bf5f7c6	svq3: move the pred mode variables to SVQ3Context This will allow removing the H264Context dependency in the future.	9 years ago
Anton Khirnov	ecc31f6b08	h264: move ff_h264_check_intra[4x4]_pred_mode() to h264_parse It is shared with svq3.	9 years ago
Anton Khirnov	1877712c58	svq3: move mb_{x,y,xy} to SVQ3Context This will allow removing the H264Context dependency in the future.	9 years ago
Anton Khirnov	c2a4ca944d	svq3: eliminate write_back_intra_pred_mode() usage This function depends on the h264 internals and is so tiny that just copying the code out is the simplest replacement.	9 years ago
Anton Khirnov	c73fb9efb2	svq3: add all the required dsp contexts into SVQ3Context Stop using the H264Context ones, to allow removing the H264Context dependency.	9 years ago
Anton Khirnov	15b0517da9	svq3: make the dsp functions static There is no need for them to be extern anymore.	9 years ago

Anton Khirnov	e42ca48a8b	svq3: rip out the mb decoding code shared with h264 The ~100 lines of shared code is not worth the pain of svq3 messing with h264 internals.	9 years ago
Anton Khirnov	e481458bc3	h264: factor out pred weight table parsing into a separate file This will allow decoupling the parser from the decoder.	9 years ago

Anton Khirnov	52ec149fbe	h2645_parse: change the AVCodecContext* parameter to void* This should make it more clear that it is not supposed to be used for anything except logging.	9 years ago

Anton Khirnov	fa936a307f	hevc_parse: rename into h2645_parse This code will be shared with h264.	9 years ago
Martin Storsjö	cdb1665f70	aarch64: Make transpose_4x4H do a regular transpose Previously, ff_h264_idct_add_neon (originally in the arm version) used a non-regular transpose in order to be able to use more instructions that deal with registers as 128 bit register pairs. The aarch64 translation doesn't do it to the same extent, but brought along the same structure since it was a straight translation. This reshuffles ff_h264_idct_add_neon, bringing it closer to the C implementation, making the transpose_4x4H macro do a regular transpose, usable for other algorithms as well. Previously, the third and fourth output from transpose_4x4H were swapped, and prior to `cc29d96d5a`, the same inputs as well. In addition to just swapping the outputs, also renumber the intermediate registers for better readability (making the register order match transpose_4x8B). This runs with the same number of cycles as before. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Ico Doornekamp	edf54887e2	rtpdec_jpeg: fix low contrast image on low quality setting The problem is that the argument 'q' is of the type uint8_t. According to the JPEG standard, if 1 <= q <= 50, the scale factor 'S' should be 5000 / Q. Because the create_default_qtables() reuses the variable 'q' to store the result of this calculation, for small values of q < 19, q wil subsequently overflow and give wrong results in the calculated quantization tables. Instead, use a new variable 'S' (same name as in RFC2435) with the proper range to store the result of the division. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago

Vittorio Giovara	68127e1bf8	intrax8: Keep a reference to the context idctdsp Use it instead of the embedded mpegvideo one. Update init function signature to load it directly from the callers.	9 years ago
Vittorio Giovara	65127450ad	intrax8: Make x8_init_block_index not use mpegvideo fields	9 years ago
Vittorio Giovara	922b7e6d86	intrax8: Use local destination buffers These buffers are just a way to store frame pointers and be able to modify them without touching the original ones. The two dependent decoders (WMV2 and VC1) do not need special care for these fields: the former does not seem to use the dest buffers, while the latter reinits them every time to the current frame data buffers. So only keep a local copy rather than the one from mpegvideo.	9 years ago

Martin Storsjö	3ee2ec5ec1	unix: Use rw_timeout for setting the connect timeout Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Martin Storsjö	136c3438bb	tcp: Use rw_timeout for setting the connect/listen timeouts Apply the default value for timeout in code instead of via the avoption, to allow distinguishing the default value from the user not setting anything at all. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Martin Storsjö	fab8156b2f	avio: Copy URLContext generic options into child URLContexts Since all URLContexts have the same AVOptions, such AVOptions will be applied on the outermost context only and removed from the dict, while they probably make sense on all contexts. This makes sure that rw_timeout gets propagated to the innermost URLContext (to make sure it gets passed to the tcp protocol, when opening a http connection for instance). Alternatively, such matching options would be kept in the dict and only removed after the ffurl_connect call. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago

Martin Storsjö	933dec0e29	file: Add an option for following a file that is being written Using this requires setting the rw_timeout option to make it terminate, alternatively using the interrupt callback (if used via the API). Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
Andrey Utkin	ccea588f83	avio: Add an option 'rw_timeout' If set non-zero, this limits duration of the retry_transfer_wrapper() loop, thus affecting ffurl_read*(), ffurl_write(). As soon as one single byte is successfully received/transmitted, the timer restarts. This has further changes by Michael Niedermayer and Martin Storsjö.

Martin Storsjö	d44f3e4059	avio: Apply avoptions on the URLContext itself as well Currently the list of avoptions for URLContext is empty though, but such options will be added. Signed-off-by: Martin Storsjö <martin@martin.st>	9 years ago
