They're short enough that inlining them actually reduces code size due to all the overhead associated with making a function call. Signed-off-by:

"language" is not an offical matroska tag. Track languages are specified with the MATROSKA_ID_TRACKLANGUAGE ebml. Writing the tag overrides the ebml specified language during playback with libav and some other players. Signed-off-by:

CID 1256 is specified as using the same table for luma and chroma, which is the same as CID 1235 luma table. This is consistent with the format supposedly being RGB, although most sequences seem to actually be YCbCr-encoded. Signed-off-by:

Convert them to zigzag order, as the rest of them are. When I was adding support for 10-bit DNxHD, I just copy-pasted the missing quant matrices from the spec. Now it turns out the existing matrices in dnxhddata.c were in zigzag order. This resulted in wrong quantization for 10-bit DNxHD. The attached patch fixes the problem by converting 10-bit quant matrices to zigzag order. Signed-off-by:

When forwarding the frame type information, by default x264 can decide which kind of keyframe output, add an option to force it to output IDR frames in to support use-cases such as preparing the content for segmented streams formats.

These field are difficult to interpret, and are provided by a single encoder (mpegvideoenc). In general they do not belong to a structure containing raw data only, so remove them from AVFrame. Mpegvideoenc now uses a private field in Picture for its internal computations. Signed-off-by:

This bit is 1 in some samples, and seems to coincide with interlaced mbs and CID1260. 2008 specs do not know about it, and maintain qscale is 11 bits. This looks oversized, but may help larger bitdepths. Currently, it leads to an obviously incorrect qscale value, meaning its syntax is shifted by 1. However, reading 11 bits also leads to obviously incorrect decoding: qscale seems to be 10 bits. However, as most profiles still have 11bits qscale, the feature is restricted to the CID1260 profile (this flag is dependent on a higher-level flag located in the header). The encoder writes 12 bits of syntax, last and first bits always 0, which is now somewhat inconsistent with the decoder, but ends up with the same effect (progressive + reserved bit). Signed-off-by:

Note that convergence_duration had another meaning, one which was in practice never used. The only real use for it was a 64 bit replacement for the duration field. It's better just to make duration 64 bits, and to get rid of it. Signed-off-by:

File libopenh264enc.c has been modified so that the encoder uses av_log() to log messages (error, warning, info, etc.) instead of logging them directly to stderr. At the time the encoder is created, the current libav log level is mapped to an equivalent libopenh264 log level. This log level, and a message logging function that invokes av_log() to actually log messages, are then set on the encoder. This contains further changes and simplifications by Michael Niedermayer and Martin Storsjö. Signed-off-by:
