0629f6128e avconv: rename transcode_audio/video to decode_audio/video. 
Those functions do only decoding now, encoding is run from
poll_filters().

74b961db77 avconv: replace -vsync cfr code with the fps filter. 
Invented timestamps for the h264 tests return to something resembling
sanity.

In the idroq-video-encode test when converting 25 fps -> 30 fps the
fifth frame gets duplicated instead of the sixth.

01e98b1b00 avconv: fix behavior with -ss as an output option. 
Don't return from poll_filters() immediately, there may be other frames
and/or other streams to handle.

Fixes a memleak.

369cb092ec avconv: add support for audio filters. 
The FATE changes are all off-by-one due to different rounding being used
(lrintf vs av_rescale_q).

720c6b78d1 buffersrc: add av_buffersrc_write_frame(). 
It's the same as av_vsrc_buffer_add_frame(), except it doesn't take pts
or pixel_aspect parameters. Those are read from AVFrame.

Deprecate av_vsrc_buffer_add_frame().

4f1500689d avconv: use lrint() for rounding double timestamps 
Converting the double to float for lrintf() loses precision when
the value is not exactly representable as a single-precision float.
Apart from being inaccurate, this causes discrepancies in some
configurations due to differences in rounding.

Note that the changed timestamp in the vc1-ism test is a bogus,
made-up value.

d8b06521a9 avconv: check for an incompatible changing channel layout 
The decoder can change the layout and channel count during decoding,
but currently we only validate that the two are compatible when opening
the codec. This checks for incompatibilities after each decoded frame.

b1041f8048 avconv: only set the "channels" option when it exists for the specified input format

"channels" option was not found.

6c9eac1998 avconv: don't set output width/height directly from input value. 
Always take it from lavfi. This way we don't need a clearly defined
corresponding input stream.

e77c86629f avconv: move resample_{width,height,pix_fmt} to InputStream.

2e21526790 avconv: change {input,output}_{streams,files} into arrays of pointers. 
Right now, they are arrays of structs, reallocated when new
streams/files are added. This makes storing pointers to those structs
harder than necessary.

d3c59d5003 avconv: use default channel layouts when they are unknown 
If either input or output layout is known and the channel counts match,
use the known layout for both. Otherwise choose the default layout based on
av_get_default_channel_layout().

Changed some FATE references due to some WAVE files now having a non-zero
channel mask.

b073819bc9 avconv: allow '-async -1' to disable timestamp sync for audio encoding 
This will allow a workaround for cases where input timestamps are invalid or
when decoder delay of 1 packet or more confuses avconv into using the wrong
timestamps as a sync reference.

e06d2dfcde avconv: drop support for building without libavfilter. 
Since the mandatory memcpy in vsrc_buffer has been eliminated, there
shouldn't be any significant reason to build without lavfi anymore.

This will make upcoming support for complex filtergraphs easier to do.
