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	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	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.

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.

wm4	05f66706d1	lavc: introduce a new decoding/encoding API with decoupled input/output Until now, the decoding API was restricted to outputting 0 or 1 frames per input packet. It also enforces a somewhat rigid dataflow in general. This new API seeks to relax these restrictions by decoupling input and output. Instead of doing a single call on each decode step, which may consume the packet and may produce output, the new API requires the user to send input first, and then ask for output. For now, there are no codecs supporting this API. The API can work with codecs using the old API, and most code added here is to make them interoperate. The reverse is not possible, although for audio it might. Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
