7c1f6df4b5 rmdec: correct DTS calculation in RealMedia container. 
First, container stores only DTS and not PTS as it was believed.
Second, multiple frames in a packet store timestamp instead of position
after the frame length.

331971116d rv10/20: tell decoder to use edge emulation 
This removes out-of-edge motion compensation artifacts (easily spotted green
blocks in avplay, gray blocks in transcoding), for example here:

6cd9d0f77d Revert "avconv: use stream copy by default when possible." 
This reverts commit 4f4f33844a.

This commit has some ugly corner cases and needs to be discussed
further.

7f5bf4fbaf flvenc: use int64_t to store offsets 
Metadata currently is written only at the start of the file in normal
cases, when transcoding from a rtmp source metadata could be
written later and the offset recorded can exceed 32bit.

f1f298cd32 Do not write ID3v1 tags by default 
ID3v1 are legacy tags with several limitations; furthermore
avconv/ffmpeg writes the tags in UTF-8 which probably has near-0
software support.

Add a -write_id3v1 option to be able to turn it on; disabled by default.

64db1a82d6 lavc: add audio flag to the 'b' option, deprecate 'ab'. 
Its only reason for its existence was ffmpeg's inability to properly assign
AVOptions to streams. Now this is not a problem anymore, so 'ab' should
go.

92f1940e99 avconv: replace -vcodec/-acodec/-scodec with a better system. 
The new option doesn't depend on its placement wrt -new* options (which
don't exist anymore) and works in a similar way as per-stream AVOptions.

-[vas]codec remain as aliases to -codec:[vas]

c14fe6bc99 lavf,lavd: remove all usage of AVFormatParameters from demuxers. 
AVFormatParameters are converted into corresponding private options in
av_open_input_file/stream() compat wrappers, so accessing them from

3304a1e69a swscale: add dithering to yuv2yuvX_altivec_real 
It just does that part in scalar form, I doubt using a vector store
over 2 array would speed it up particularly.

The function should be written to not use a scratch buffer.

3d4f0dab79 avconv: get rid of new* options. 
They are confusing, irregular and redundant -- -map already contains all
the information.  Stream maps can now be parsed in opt_output_file().

Add a more user-friendly default behavior in case no maps are present.

Breaks -programid for now, but it never worked properly anyway. A better
solution will be written soon.
