* Deprecate avctx.coded_frameVittorio Giovara2015-07-20
| | | | | | | | | | | | | | | | | The rationale is that coded_frame was only used to communicate key_frame, pict_type and quality to the caller, as well as a few other random fields, in a non predictable, let alone consistent way. There was agreement that there was no use case for coded_frame, as it is a full-sized AVFrame container used for just 2-3 int-sized properties, which shouldn't even belong into the AVCodecContext in the first place. The appropriate AVPacket flag can be used instead of key_frame, while quality is exported with the new AVPacketSideData quality factor. There is no replacement for the other fields as they were unreliable, mishandled or just not used at all. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* Gather all coded_frame allocations and free functions to a single placeVittorio Giovara2015-07-20
| | | | | | | | | | | | | | Allocating coded_frame is what most encoders do anyway, so it makes sense to always allocate and free it in a single place. Moreover a lot of encoders freed the frame with av_freep() instead of the correct API av_frame_free(). This bring uniformity to encoder behaviour and prevents applications from erroneusly accessing this field when not allocated. Additionally this helps isolating encoders that export information with coded_frame, and heavily simplifies its deprecation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* proresenc: Properly account for alpha planeChristophe Gisquet2014-08-18
| | | | | | | | | | The packet buffer allocation considers the alpha channel as DCT-coded, while it is actually run-coded and thus requires a larger buffer. CC: libav-stable@libav.org Signed-off-by: Diego Biurrun <diego@biurrun.de> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* proresenc: Realloc if buffer is too smallChristophe Gisquet2014-08-18
| | | | | | | | | | | | | | The buffer allocation may be incorrect (e.g. with an alpha plane), and currently causes the buffer to be set to NULL by init_put_bits, causing a crash later on. So, detect that situation, and if detected, reallocate the buffer and ask for a sample that shows the problem.

* proresenc: Don't free a buffer not owned by the codecMartin Storsjö2012-09-04
| | | | | | | | | | The data in coded_frame isn't allocated using get_buffer, but is copied from the input frame to the encoder, so we should not try to free it ourselves. This fixes an assert failure when running in debug mode. Signed-off-by: Martin Storsjö <martin@martin.st>
* proresenc: Write the full value in one put_bits callMartin Storsjö2012-09-04
| | | | | | | | | Previously, the put_bits call writing the value wrote a value larger than the number of bits specified, failing asserts in debug mode. There was no actual bitstream writer corruption, since the overwritten bit already always was set to 1. Signed-off-by: Martin Storsjö <martin@martin.st>

* prores: handle 444 chroma in right orderKostya Shishkov2012-02-29
| | | | | | | ProRes codes chroma blocks in 444 mode in different order than luma blocks, so make both decoder and encoder read/write chroma blocks in right order. Reported by Phil Barrett
* prores: use natural integer type for the codebook indexChristophe GISQUET2012-02-22
| | | | | | | | | | | The operations that use it require it to be promoted to a larger (natural) type and thus perform sign extension on it. While an optimal compiler may account for this, gcc 4.6 (for x86 Windows) fails. Using the natural integer type provides a 2% speedup for Win64 and 1% for Win32.

* proresenc: force bitrate not to exceed given limitKostya Shishkov2012-02-18
| | | | | | Apple ProRes Format Specifications mentions target data size for every frame, so make sure frame meets it. This also allows encoder to demand much smaller packet sizes for output.
