The previous name is misleading, because the function does not actually
initialize any filters - it creates a new output stream and binds a
filtergraph output to it.
Their only function is checking that encoding was not specified for
data/unknown-type streams, but the check is broken because enc_ctx will
not be created in ost_add() unless a valid encoder can be found.
Add an actually working check for all types for which encoding is not
supported in choose_encoder().
ts_discontinuity_detect() is applied right after demuxing, while
InputStream.pts is a post-decoding timestamp, which may be delayed with
respect to demuxing by an arbitrary amount (e.g. depending on the thread
count when frame threading is used).
The name is misleading, because it is not a picture in the sense of MPEG
terminology (which define "picture" as "frame or field"), but always a
full frame. 'next' is also redundant and/or misleading, because it is
the _current_ frame to be encoded.
Previously they would only be used with trivial filtergraphs, because
filters did not handle frame durations. That is no longer true - most
filters process frame durations properly (there may still be some that
don't - this change will help finding and fixing them).
Improves output video frame durations in a number of FATE tests.
When an encoder exports sum-of-squared-differences information in
encoded packets, print_report() will print PSNR information in the
status line. However,
* the code computing PSNR assumes 8bit 420 video and prints incorrect
values otherwise; there are no issues on trac about this
* only a few encoders (namely aom, vpx, mpegvideo, snow) export this
information; other often-used encoders such as libx26[45] do not
export this, even though they could
This suggests that this feature is not useful and it is better to remove
it rather than spend effort on fixing it.
Otherwise main and overlay videos share the same input region. Note NULL
pointer imples the whole overlay video will be processed.

When write multi-trun box, the MOV_TRUN_FIRST_SAMPLE_FLAGS flag
need judge by first param, not 0.
If the original video contains consecutive I frames,
this will cause the packets of fmp4 have error sample_flags ,
and then incorrect keyframes were generated,
and then error packet will be seeked.

framebuf is only allocated when the new width/height are larger than the old
but nothing sets the old so its always allocated.
Use av_fast_mallocz() instead.

The change introduced in b18a9c2971
created a regression for non-subsampled progressive RGB jpegs. This
should fix that.
Additionally, this should fix other RGB JPEGs broken before the recent
patches, such as those in Trac issue #10190.
When enable lcms2, the fate-png-icc-parse will get error bellow.

This because updated how PNG handles colors (no
longer using mastering display metadata for that).
