A pix_fmt_mask is obtained by bitwise or-ing two pixel format bits,
rather than doing a logical or.

This fixed the problem where if there's more than 64 pixel formats
defined avcodec_find_best_pix_fmt() returns the wrong pixel format.

this more than 4000 line file has less than 600 lines that are not in ffmpeg.c
and they are largely cosmetic changes from ffmpeg.c.
Thus the copyright statement from ffmpeg.c should be used.

This way the content of "vfilters" can be reused.

For example when the frame size changes, the filterchain is
reconfigured reusing again the vfilters value.

Use av_log(AV_LOG_LEVEL...) rather than av_dlog, the log is useful
even for "normal" debugging, and consistent with what is done in
ffmpeg.

Also change the message to achieve better consistency with the
corresponding ffmpeg message.

Sligthly improve readability, reduce redundancy.

Use the value specified in the codec context for setting the
filterchain sample aspect ratio, when it is not specified in the
stream context.

Consistent with the ffmpeg behavior.

Fix trac issue #398.

avcodec_set_dimensions should be used for size changes to ensure
compatibility with future changes.
avctx->width/avctx->height may not be set to display-only dimensions.
Even more so since vc1dec.c would later set coded_width/height based
on this.
coded_width/coded_height should be used instead of width/height for
decoder setup.
This fixes playback of e.g. zz-mcr-nsqr.vc1 sample (containing
display width/height settings) in MPlayer and should fix a crash
with MPC: http://forum.doom9.org/showthread.php?t=162221.

This reverts commit 4f4f3384.

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

It allows to check if a given codec can be written into a container.

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.

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.

New streams are always added to the last output file.

Move find_codec_or_die(), choose_codec(), new_output_stream() and
read_avserver_streams() below transcode() where they belong.

It's only used in opt_output_file(), so move it right above
opt_output_file().

parse_forced_key_frames() is only used in new_video_stream(), so move it
right above new_video_stream().

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.

It's often mistakenly used as 'same quality', emphasize that it's not
true in the manual.

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]
