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:

This reverts commit 7bb1c1bf. A long existing version in the form of avconv -h decoder=h264 already existed, and this just duplicates it.

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:

Even though libmfx might not need them anymore, avcodec might still access the surfaces. So free them separately at the end.

The System V ABI on x86-64 specifies that the al register contains an upper bound of the number of arguments passed in vector registers when calling variadic functions, so we aren't allowed to clobber it. checkasm_fail_func() is a variadic function so also zero al before calling it. Signed-off-by:

Tested functions are internally kept in a binary search tree for efficient lookups. The downside of the current implementation is that the tree quickly becomes unbalanced which causes an unneccessary amount of comparisons between nodes. Improve this by changing the tree into a self-balancing left-leaning red-black tree with a worst case lookup/insertion time complexity of O(log n). Significantly reduces the recursion depth and makes the tests run around 10% faster overall. The relative performance improvement compared to the existing non-balanced tree will also most likely increase as more tests are added. Signed-off-by:

This works only for extradata sizes up to 128 bytes. Additionally, I could never actually see it doing anything. The new code using MMAL_BUFFER_HEADER_FLAG_CONFIG now takes care of this. Signed-off-by:

We can send mp4-style data directly. But for some reason, this requires sending the extradata as buffer with MMAL_BUFFER_HEADER_FLAG_CONFIG set. Reuse the infrastructure for sending AVPackets to do this. Signed-off-by:

Add an allowed parameter to -h and --help avconv option to print private options from a codec, format, or filter, named with the provided input value. In case multiple classes are found (eg. mov demuxer and mov muxer, or h264 decoder and h264 demuxer) print all options from all classes. It is possible to select the type of class to print by adding it before the name (eg. demuxer:mov and muxer:mov, or decoder:h264and demuxer:h264). Signed-off-by:
