This commit is plain wrong, theres no reason to error out at this point nor is the
error value guranteed to be negative as it should be

Replace:
s->last_picture_ptr->f.key_frame = 0;
with:
s->last_picture_ptr->key_frame = 0;

This is required since mpegvideo.h:Picture now contains an embedded
AVFrame f, rather than a literal copy of the AVFrame fields.

We use this flag to tell when to assume decoded data is free
from artifacts after a seek. The mpeg1/2 decoder will generate
a dummy frame if decoding is started on a non keyframe. This
will sadly be output from decoder to player and displayed
as a gray screen.

libavcodec/libspeexdec.c:108: warning: passing argument 2 of ‘speex_bits_read_from’ discards qualifiers from pointer target type
/usr/include/speex/speex_bits.h:80: note: expected ‘char *’ but argument is of type ‘const uint8_t *’

libavcodec/libopenjpeg.c:100: warning: passing argument 2 of ‘opj_cio_open’ discards qualifiers from pointer target type
/usr/include/openjpeg.h:770: note: expected ‘unsigned char *’ but argument is of type ‘const uint8_t *’

User-provided data should never trigger an assert; return error instead.
Also fix an instance of get_bits where get_bits_long should have been used.

This eliminates the following warning:
libavcodec/vaapi_mpeg2.c:112:14: warning: variable 'start_code' set but not used

An official specification now exists and it is both more detailed and
easier to understand than the incomplete notes available here.

The filter was integrated natively into libavfilter as a source with
name rgbtestsrc.

The licence was changed from GPL to LGPL with explicit approval from
the original author.

See thread:
Subject: [FFmpeg-devel] [PATCH] lavfi: add rgbtestsrc source,
        ported from MPlayer libmpcodecs
Date: Mon, 11 Jul 2011 16:32:41 +0200

In particular creates a special test_init function, which calls a
common init, and introduces a fill_picture_fn which points to the
filling function.

This is required by the pending patch for adding the rgbtestsrc
source.

It is natively included in libavfilter.
