Vittorio Giovara 419e3404d0 mpegvideo: Drop exchange_uv() function and use its code directly 
Code is small enough that there is no advantage in a separate function.

Vittorio Giovara 4e17946f10 mpegvideo: Rework various functions not to use MpegEncContext directly 2015-05-22 15:34:39 +01:00
Vittorio Giovara a3f4c930ac mpegvideo: Have ff_mpeg_ref_picture use AVCodecContext directly 2015-05-22 15:34:39 +01:00
Vittorio Giovara d528045558 mpegvideo: Have ff_mpeg_unref_picture use AVCodecContext directly 
This skips setting the memory to 0 but allows for reuse on different
contextes. Oracle did not report any unsual activity because of it.

It is just a duplicate of an AVCodecContext member so use it instead.

Vittorio Giovara eafbc6716c vmnc: Delay pixel size check 
Some clients incorrectly set 24 as bits_per_coded_sample, while
the actual value is preserved in one of the codec headers.
In order to work around this, delay the check until decode_frame().

Vittorio Giovara 04070dbca0 libx265: Fix 'braces around scalar initializer' warning 
x265 Reordered the x265_picture fields in the commit

https://github.com/videolan/x265/commit/51b1518de2414431f36eac592db15b667c25a7b9#diff-945b5354d8767dfac13334f2d22cf58fR107

Vittorio Giovara 34efb8a169 quickdraw: Support direct pixel blocks 
Data is stored in separated components so rework decode_rle() to support
stepping and offsets.
 2015-05-06 14:27:34 +01:00
Vittorio Giovara bb2cb0a66d quickdraw: Switch to greedy parsing 
Quickdraw packs data as a series of codes that the application is supposed
to handle, but it does not define any order in which they might appear.
Since it's unfeasible to support *all* opcodes defined by the spec,
only handle well-known blocks containing video data and ignore any unknown
or unsupported ones.

Move palette loading and rle decoding to separate functions to resue them
in other blocks and drop format initialization in init since it can
support more formats than pal8.

Validate width and height.

absolute filesystem path from the mount point.
