* snappy: Refactor so ff_snappy_uncompress() uses an existing bufferTom Butterworth2015-07-233-13/+37
| | | | | | Some uses of Snappy require uncompressing to positions within an existing buffer. Also adds a function to get the uncompressed length of Snappy data.
* hap: Fix slice size computationTom Butterworth2015-07-232-10/+18
| | | | | | | | A bug was introduced in 977105407cae55876041dddbf4ce0934cdd4cd6c whereby when frame height wasn't divisible by the number of threads, pixels would be omitted from the bottom rows during decode. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* Deprecate avctx.coded_frameVittorio Giovara2015-07-2047-4/+251
| | | | | | | | | | | | | | | | | 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>
* Add a quality factor packet side dataVittorio Giovara2015-07-208-3/+47
| | | | | | | | This is necessary to preserve the quality information currently exported with coded_frame. Add the new side data to every encoder that needs it, and use it in avconv. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* Gather all coded_frame allocations and free functions to a single placeVittorio Giovara2015-07-2049-419/+17
| | | | | | | | | | | | | | 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>

* a64multienc: Do not entangle coded_frameVittorio Giovara2015-07-201-6/+5
| | | | | | | | | | | This change (and the following ones of the same kind) is mainly to simplify wrapping this section with an #if FF_API block later on. No functional changes are applied, the fields of the context coded_frame fields are directly initialized, instead of keeping a reference to the coded_frame itself.

| | | | | | | | | The upper halves are not guaranteed to be zero in x86-64. Also use `test` instead of `and` when the result isn't used for anything other than as a branch condition, this allows some register moves to be eliminated. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
