2012-09-19doc/filters: clarify use of graph2dotTim Nicholson
The GRAPH_DESCRIPTION string supplied to graph2dot must include explicitly defined inputs and outputs which are not normally part of the command line used in a real invocation. This clarifies that requirement, and provides an example. Signed-off-by: Stefano Sabatini <stefasab@gmail.com>

2012-09-13examples/decoding_encoding: replace "picture" with "frame" in encode_example()Stefano Sabatini
The use of "picture" in place of "frame" is confusing.

2012-09-11examples/muxing: apply misc fixes to log messagesStefano Sabatini
2012-09-11examples/muxing: rename img_convert_ctx to sws_ctxStefano Sabatini
The new name is more consistent with the codebase, and more self-consistent with the libswscale API.
2012-09-11examples/muxing: merge some declarations and definitionsStefano Sabatini
2012-09-11examples/muxing: prefer AVPicture to AVFrame, when feasibleStefano Sabatini
Favor the use of plain AVPicture over AVFrame, especially when the use of AVFrame is not required like in the case of tmp_picture. Also adopt more straightforward names, to avoid frame/picture confusion.
2012-09-11examples/demuxing: add audio decoding/demuxingStefano Sabatini
2012-09-11lavf/segment: add segment_list_flags optionStefano Sabatini
Allow to specify options affecting the segment list generation. In particular: add +live and +cache flags. For a full discussion read trac ticket #1642: http://ffmpeg.org/trac/ffmpeg/ticket/1642 Also add live M3U8 generation example.
2012-09-11ffprobe: add print_section option to the compact writerStefano Sabatini
Allow to skip section name at the begin of each line. Possibly simplify output.
2012-09-10lavfi/setpts: add FRAME_RATE constantStefano Sabatini
Useful for dealing with constant frame-rate video.

The native filter transpose is perfectly equivalent.
2012-09-06lavu/parseutils: add av_small_strptime()Stefano Sabatini
Make internal small_strptime() function public, and use it in place of strptime(). This allows to avoid a dependency on strptime() on systems which do not support it. In particular, fix trac ticket #992.
2012-09-05Optimization of AC3 floating point decoder for MIPSNedeljko Babic
FFT in MIPS implementation is working iteratively instead of "recursively" calling functions for smaller FFT sizes. Some of DSP and format convert utils functions are also optimized.
