Andreas Rheinhardt 1e6307f46c avcodec/encode, frame_thread_encoder: Unify calling encode callback 
The encode-callback (the callback used by the FF_CODEC_CB_TYPE_ENCODE
encoders) is currently called in two places: encode_simple_internal()
and by the worker threads of frame-threaded encoders.

After the call, some packet properties are set based upon
the corresponding AVFrame properties and the packet is made
refcounted if it isn't already. So there is some code duplication.

There was also non-duplicated code in encode_simple_internal()
which is executed even when using frame-threading. This included
an emms_c() (which is needed for frame-threading, too, if it is
needed for the single-threaded case, because there are allocations
(via av_packet_make_refcounted()) immediately after returning
from the encode-callback).

Furthermore, some further properties are only set in
encode_simple_internal(): For audio, pts and duration are derived
from the corresponding fields of the frame if the encoder does not
have the AV_CODEC_CAP_DELAY set. Yet this is wrong for frame-threaded
encoders, because frame-threading always introduces delay regardless
of whether the underlying codec has said cap. This only worked because
there are no frame-threaded audio encoders.

This commit fixes the code duplication and the above issue by factoring
this code out and reusing it in both places. It would work in case
of audio codecs with frame-threading, because now the values are
derived from the correct AVFrame.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.
