--------------------------------------
dschmidt opened a new pull request, #2984:
URL: https://github.com/apache/tika/pull/2984
JIRA: https://issues.apache.org/jira/browse/TIKA-4802
`MP4Parser` reads the average audio bitrate from the sound track's `esds`
(TIKA-4779) but does not expose the video track's bitrate. A new
`TikaMp4VideoHandler` (mirroring `TikaMp4SoundHandler`) reads the average
bitrate from the video sample entry's `btrt` BitRateBox and sets it as
`video:bitrate`.
Tested against a 1.8 KB ffmpeg-generated clip (`testMP4Video.mp4`, `btrt`
avgBitrate 6536). The `esds` path (legacy MPEG-4 Part 2 video) is out of scope;
modern H.264/HEVC carry the bitrate in `btrt`.
Overlaps #2982 (TIKA-4800), which adds the same `Video.java` and
`testMP4Video.mp4` fixture; whichever merges second has a trivial rebase.

> MP4Parser reads the average audio bitrate from the sound track's esds
> (TIKA-4779) but does not expose the video track's bitrate. The ISO BitRateBox
> (btrt), a child of the visual sample entry, carries the average and maximum
> bitrate and is written by common H.264/HEVC encoders. Expose the average as
> video:bitrate, mirroring audio:bitrate.
