This allows using more specific implementations for chroma/luma, e.g.
we can make assumptions on filterSize being constant, thus avoiding
that test at runtime.

This allows sharing them between multiple .asm files.

Keep a per-OutputFile instance of it, thus making -ss work with multiple
output files.

Keep a per-OutputFile instance of it, thus making -t work with multiple
output files.

Instead store output streams in the same way as input streams.

Move the stream specifier to the option name.

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.

This removes out-of-edge motion compensation artifacts (easily spotted green
blocks in avplay, gray blocks in transcoding), for example here:

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.

MpegTSContext's AVClass member can be NULL.

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().
