The main change is that we wait with opening the muxer ("writing
headers") until we have data from all streams. This fixes race
conditions at init due to broken assumptions in the old code.
This also changes a lot of other stuff. I found and fixed a few API
violations (often things for which better mechanisms were invented, and
the old ones are not valid anymore). I try to get away from the public
mutex and shared fields in encode_lavc_context. For now it's still
needed for some timestamp-related fields, but most are gone. It also
removes some bad code duplication between audio and video paths.

#########################
|
|
#
|
|
# Note: by default, this file is installed to /etc/mpv/encoding-profiles.conf
|
|
# (or a different location, depending on --prefix). mpv will load it by
|
|
# default on program start. If ~/.mpv/encoding-profiles.conf exists, this file
|
|
# will be loaded instead.
|
|
#
|
|
# Then, list all profiles by
|
|
# mpv --profile=help | grep enc-
|
|
#
|
|
# The following kinds of encoding profiles exist:
|
|
# enc-a-*: initialize an audio codec including good defaults
|
|
# enc-v-*: initialize a video codec including good defaults
|
|
# enc-f-*: initialize a file format including good defaults, including
|
|
# selecting and initializing a good audio and video codec
|
|
# enc-to-*: load known good settings for a target device; this typically
|
|
# includes selecting an enc-f-* profile, then adjusting some
|
|
# settings like frame rate, resolution and codec parameters
|
|
#
|
|
# AFTER including a profile of these, you can of course still change
|
|
# options, or even switch to another codec.
|
|
#
|
|
# You can view the exact options a profile sets by
|
|
# mpv --show-profile=enc-to-hp-slate-7
|
|
#
|
|
# Examples:
|
|
# mpv --profile=enc-to-dvdpal --o=outfile.mpg infile.mkv
|
|
# mpv --profile=enc-f-avi --ofps=30 --o=outfile.avi infile.mkv
|
|
# mpv --profile=enc-v-mpeg4 --ovcopts-add=qscale=7 --profile=enc-a-mp3 --oacopts-add=b=320k --o=outfile.avi infile.mkv
