The ASS margins are utilized to generate percentual values, as
the usage of cell-based sizing and offsetting seems to be not too

Apparently for various image sequences libavformat/utils.c can
calculate rather fancy r_frame_rate values, such as `186/1921`,
and since ffmpeg.c utilizes r_frame_rate for the filter chain
time base, this can quite deteriorate the output frame timing - even
though the user has requested the image

Unlike libx264, libx265 does not have a separate "unspecified"/"auto"
default for color range, so we do always have to specify it.
Thus, we are required to handle the RGB case on the libavcodec
side to enable the correct value to be written out in in case
of RGB content with unspecified color
By default the x264 full range flag is set to -1. By not setting
it to something else, we can let libx264 handle the RGB case.
Additionally, change the preference order to user-specified range
first, and then any fall-back logic left for the YUVJ pix_fmts.
Fixes the capture part of #9374

Unlike libx264, libx265 does not handle the chroma format check
on its own side, so in order to not write out values which are
supposed to be ignored according to the specification, we limit
the writing out of chroma sample location to 4:2:0 only.

Now both current usages utilize an already found descriptor.

Yea, FATE passes :) . I think this stuff not being noticed until now
is due to nothing checking the metadata values returned by vf_scale
(since pix_fmt and actual logic is not changed at all with these

Thanks, applied this patch as 06ce821bc7622c1394c5179fb69cabf02dd24869 .
Now it's just the chroma location coding bits.

This information is coded in a standard MP4 KindBox and utilizes the
scheme and values as per the DASH role scheme defined in MPEG-DASH.
Other schemes are technically allowed, but where multiple schemes
define the same concepts, the DASH scheme should be utilized
unused variables causing additional warnings were removed.
Best regards,

Unfortunately the current production versions of this software
do not 100% adhere to the CMAF specification, and have decided
to utilize the HTML5 media track identifier for audio descriptions.
This way the default mode of operation is according to the CMAF
specification
to deduplicate

create mode 100644 libavformat/ttmlenc.h
From: Jan Ekström
Includes basic support for both the ISMV ('dfxp') and MP4 ('stpp')
methods. This initial version also foregoes fragmentation support
in case the built-in sample squashing is to be utilized, as this
eases the initial review.
Additionally, add basic tests for both muxing modes
In 1c42fd93236e7869ef4d9fe3650dd3e951387321 the ipcm identifier was
added in order to demux additional raw audio from Sony MP4 files.
Unfortunately, it was not noticed that this same list is utilized
for muxing as well, thus causing ipcm to get preferred compared
to the identifier officially
