vp8: always update next_framep[] before returning from decode_frame().
Also slightly move around code not allocate a new frame if we won't
decode it. This prevents us from putting undecoded frames in frame
pointers, which (in mt decoding) other threads will use and wait on
as references, causing a deadlock (if we skipped decoding) or a crash
(if we didn't initialized next_framep[] at all).

avconv: better next_dts usage.
next_dts is used for estimating the dts of the next packet if it's
missing. Therefore, it makes no sense to set it from the pts of the last
decoded frame. Also it should be estimated from the current packet
duration/ticks_per_frame always, not only when a frame was successfully
decoded.

avconv: reduce overloading for InputStream.pts.
It currently has different meanings at different times (dts of the last
read packet/pts of the last decoded frame). Reduce obfuscation by
storing pts of the decoded frame in the frame itself.
Anton Khirnov [Sun, 5 Feb 2012 13:32:10 +0000 (14:32 +0100)]
avconv: rework -t handling for encoding.
Current code compares the desired recording time with InputStream.pts,
which has a very unclear meaning. Change the code to use actual
timestamps of the frames passed to the encoder.
In several tests, one less frame is encoded, which is more correct.
In the idroq test one more frame is encoded, which is again more
correct.

avconv: set encoder timebase for subtitles.
The actual number (1/1000) will probably require some
discussion/tweaking in the future, but should be good enough for now,
since the timestamps in AVSubtitle are in this timebase by definition.

pva-demux test: add -vn
The output is obviously not supposed to contain video (since only
-acodec copy is specified), but that only happens because of the way -t
handling is implemented currently.

apedec: allow the user to set the maximum number of output samples per call
It makes sense in some cases to split up the output packet to save on memory
usage (ape frames can be very large), but the current/default size is
arbitrary. Allowing the user to configure this gives more flexibility and
requires minimal additional code.

ape: calculate final packet size instead of guessing
Calculates based on total file size and wavetaillength from the header.
Falls back to multiplying finalframeblocks by 8 instead of 4 so that it will
at least be overestimating for 24-bit. Currently it can underestimate the
final packet size, leading to decoding errors.

drawtext: add 'fix_bounds' option on coords fixing
Before, drawtext filter deliberately altered given text coordinates if
text didn't fully fit on the picture. This breaks the use case of
scrolling large text, e.g. movie closing credits.
Add 'fix_bounds', to make it usable in such cases (by setting its value to 0).
Default behavior is not changed, and non-fitting text coords are fixed.
It would never be called when the searched-for position
was already in the index.
In the other cases, the ogg_reset at the end of the
read_timestamp function handled it.
oggdec: fix keyframe seeking when granule_is_start is 0.
In this case, the pts values will be delayed by one, but
at the same time pts values might only be supplied for e.g.
keyframes.
This results on only the frame after the keyframe having a
pts value.
As a hack, make read_timestamp return the keyframe position
together with the pts from a following frame when seeking
to a keyframe.
Fixes trac issue #438.
However it causes the read_timestamp function to return a
pos value that is actually before the packet with the
indicated pts.
We can handle v4 just fine, the parts we currently use
are the same for v3 and v4.
v4 can in addition contain an index which we so far do
not use though.
Fixes trac issue #438.
Seeking in that sample would cause ogg_read_timestamp to fail
because ogg_packet would go into a state where all packets
of stream 1 would be discarded until the end of the stream.

Line sizes are only 8-byte aligned, so use unaliged loads
for add_bytes_l2 pointers.
Increasing the alignment requirement to 16 seemed a bit extreme
(png may be used for rather small sizes).
Also fix a mov that had its arguments swapped, leading
add_bytes_l2 being applied on up to 8 bytes too few.
