Having it there forces decoding of a frame in order to get frame_size, but it
is not really needed for proper demuxing or decoding.

The first timestamp should be negative due to delay.
Also, do not set AVCodecContext.frame_size unnecessarily.

Using AVCodecContext.frame_size is not reliable.

It prevents leaving the AVPacket uninitialized.

Seems to fix trac issue #569.
Sample is unfortunately not available, but it might be caused by
an index existing for non-existing audio stream (?).

Manual replacements are done in this commit.

In many cases, the id is some constant made up number (e.g. 0 for video
and 1 for audio), which is then not used in the demuxer for anything.
Those ids are removed.

Trivial replacements with sed are done in this commit:
sed 's/av_new_stream(\([^)]*\), 0)/avformat_new_stream(\1, NULL)/'

It takes a codec parameter, thus enabling codec-specific defaults.

Fixes ticket #550.

Add a wrapper for libutvideo's decoder.

This supports decoding the following FOURCCs:
    ULY0 - 4:2:0 YCbCr
    ULY2 - 4:2:2 YCbCr
    ULRG - RGB
    ULRA - RGBA

Also, bump version.

This allows setting the filter_src option for these demuxers, too,
which wasn't possible at all before (where the option only was set
via URL parameters for RTSP).

This helps sharing these options with the sdp and rtp demuxers.

avconv doesn't map video streams to a muxer without specifying a
manual stream mapping if the default video codec is CODEC_ID_NONE.

It was broken in 3b3ea34655
"Remove all uses of deprecated AVOptions API", where any
presence of a payload_type AVOption caused its value to
be returned, even if it wasn't set (and thus had the default
-1 value).

This caused the RTP muxer to be broken.

Read it as a flag from the flags field instead.

Eventually, the old way of passing options by adding
stuff to the URL can be dropped.

This avoids having to tamper with the user-specified URL to
pass options on the transport mode. This also works better
with redirects, since the options don't need to be parsed out
from the URL.

Use defines for shortening common parts, omit the .dbl named
initializer (since it's the first element in the union).

This eases adding options that are common for both. The
AV_OPT_FLAG_EN/DECODING_PARAM still indicates whether they belong
to the muxer or demuxer.

Deprecate AVFormatContext.mux_rate.

It's too unreliable to be useful. avio_size() should be called instead.

The cbSize field should be included in all cases, even with PCM where
its value is ignored.

Fixes encoding PCM audio in Matroska for some players which insist on
a full WAVEFORMATEX structure for A_MS/ACM audio.

Since fate uses wav files for the audio test a larger number of tests
has changed checksums or shifted positions due to the 2 byte longer
wave header.
