Rename it to AVDictionary, since it will be used as such. Tags
documentation and metadata conversion API is lavf-specific, so remains
there.

The options -loglevel LEVEL -debug FLAGS can be used for achieving the
same objectives, with a finer level of control.
|
|
Use -vismv 1 instead. Simplify.
|
|
|
|
Deprecate av_get_bits_per_sample_fmt(), which was a misnamed function.
For the moment we don't have sample formats with a non-integer number
of bytes, in that case we may need to create a new
av_get_bits_per_sample() function. In the meanwhile we prefer to adopt
this variant, since avoids divisions by 8 all over the place.
|
|
It is a more search-friendly alternative to the ^ operator.
|
|
Remove AVFilterBufferRefAudioProps.size, and use nb_samples in
avfilter_get_audio_buffer() and avfilter_default_get_audio_buffer() in
place of size.
This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.
|
|
This is consistent with the order of parameters in
av_samples_fill_arrays().
|
|
_fill_arrays()
The new layout is consistent with that of the av_image_() API, and
simplifies understanding and copy operations, it also preserves
alignment information which was lost with the previous layout.
This breaks API/ABI, but since the function was never referenced in
the code (and it isn't unlikely already used by someone) then this
should not be a problem.

The new flags parameter allows to specify if the video ref to add
should overwrite the cache, if the flag is not set vsrc_buffer will
complain and abort; otherwise it will clean the already cached video
ref before to overwrite it, thus avoiding a leak.
|
|
|
|
Useful for mimicking the ffmpeg -i FILE syntax.
|
|
|
|
This allows a more efficient use of the commandline.
|
|
Allow to free the buffers cached in each AVFilterLink pool.
Fix leak.

Rename:
api-example.c -> encoding-example.c
output-example.c -> muxing-example.c
|
|
Documents the mapping from FFmpeg options to libvpx.
|

This adds basic stream format support and allows for arbitrary bit rates
rather than just those supported in AC-3.

Remove reference to the mplayerhq.hu rsync command, and replace it
with a reference to the make fate-rsync command.
rsync needs still to be enabled on mplayerhq.hu, and it is currently
not working. Also the fate-rsync Makefile target can be easily updated
without the need to keep the docs in synch.

Channel coupling is an optional AC-3 feature that increases quality by
combining high frequency information from multiple channels into a
single channel. The per-channel high frequency information is sent with
less accuracy in both the frequency and time domains. This allows more
bits to be used for lower frequencies while preserving enough
information to reconstruct the high frequencies.

This needs work but it should not rot in soc svn.
