nu774	6ec688e1bc	mp3: enable packed main_data decoding in MP4 14496-3 suggests packing main_data of MP3 that is usually scattered into multiple frames due to bit reservoir. However, after packing main_data into a access unit, bitrate index in the MPEG audio frame header doesn't match with actual frame size. In order to accept this, this patch removes unnecessary frame size checking on mp3 decoder. Also, mov demuxer was changed to use MP3 parser only on special cases (QT MOV with specific sample description) to avoid re-packetizing.

Luca Barbato	9af7e8045e	lavc: Clarify the behaviour of dimension and format context fields The AVCodecContext width, height, coded_width, coded_height and format are used mainly as decoding hints and they get internally overwritten during the data parsing stage. Do not assume they match the last AVFrame provided by avcodec_decode_video2 and assimilated functions since multi-threading and other frame reordering might make those values to refer to frames that will be outputted in the future.

nu774	0289f81241	aac: Correctly map multichannel ADTS AAC with non-zero channel_config + PCE The decoder assigns channels using default channel configuration for 5.1ch when it parses an ADTS frame header using consecutive channel ids. When a PCE comes, it reassigns channels using PCE configuration using directly the ids provided. They can be arbitrary. Always use consecutive channel ids to avoid decoding glitches due spurious reconfigurations due the channel ids mismatch between the two otherwise-identical channel maps.

wm4	3efe0393e4	hevc: make avcodec_decode_video2() fail if get_format() fails Personally, I need the decoder to back out if get_format() returns no usable pixel format. This didn't work because the error code was not propagated down the call chain. This in turn happened because the variable declaration removed in this patch shadowed the variable, whose value is returned at the end of the function. Consequently, failures of decode_nal_unit() were ignored in this place.

Anton Khirnov	bd737b5178	h264: reset the private data in init_thread_copy() The generic code copies the main context's private data to all the others. However that is quite dangerous, as it might end up copying some pointers that are or will become invalid. Since everything we actually need will be copied later in update_thread_context(), it's safest to zero the private data in init_thread_copy(), so it works the same way as init for the main context.	2015-04-05 12:03:07 +02:00

The names of the functions are consistent with the lavu/samples API (av_samples_get_buffer_size(), av_samples_fill_arrays()). A redundant check has been dropped from av_image_fill_arrays().

Martin Storsjö	8a3d9ca603	libavcodec: Add an OpenH264 encoder wrapper Compared to existing, common opensource H264 encoders, this can be useful since it has got a different license (BSD instead of GPL). Performance- and qualitywise it is comparable to x264 in ultrafast mode. Hooking it up as an encoder in libavcodec also simplifies comparing it against other common encoders. This requires OpenH264 1.3 or newer. Since the OpenH264 API and ABI changes frequently, only releases are supported. To take advantage of the OpenH264 patent offer, the OpenH264 library must not be redistributed, but downloaded at runtime at the end-user's system.

Rémi Denis-Courmont	c220a60f92	vdpau: add helper for surface chroma type and size Since the VDPAU pixel format does not distinguish between different VDPAU video surface chroma types, we need another way to pass this data to the application. Originally VDPAU in libavcodec only supported decoding to 8-bits YUV with 4:2:0 chroma sampling. Correspondingly, applications assumed that libavcodec expected VDP_CHROMA_TYPE_420 video surfaces for output. However some of the new HEVC profiles proposed for addition to VDPAU would require different depth and/or sampling: http://lists.freedesktop.org/archives/vdpau/2014-July/000167.html ...as would lossless AVC profiles: http://lists.freedesktop.org/archives/vdpau/2014-November/000241.html To preserve backward binary compatibility with existing applications, a new av_vdpau_bind_context() flag is introduced in a further change.
