* lavc: add profiles to AVCodecDescriptorAnton Khirnov2015-12-12
| | | | | The profiles are a property of the codec, so it makes sense to export them through AVCodecDescriptors, not just the codec implementations.
* jpeg2000: Refactor decode_packetsLuca Barbato2015-09-14
| | | | Move the packet-specific parsers in separate functions.
* jpeg2000: Templatize the frame writerLuca Barbato2015-09-14

| | | | That loop is completely stand-alone.
* jpeg2000: Split codeblock decoding from the main tile decodingLuca Barbato2015-09-11
| | | | That loop is completely stand-alone.
