I have issues when I'm trying to convert Original Sony ILCE-7M4 movies to HEVC with a lower bitrate, and adding a META box / atom via MP4Box.
I do the following steps:
First I CONVert the ORIGinal File
ffmpeg -i "${ORIGFILE}" -preset faster -c:v libx265 -crf 17 -c:a aac_at -b:a 192k -movflags use_metadata_tags+faststart -map_metadata 0 -tag:v hvc1 "${CONVFILE}"
Then I add a meta box to a new PROCessed file (previously I added XML data to the meta, but this does not make any difference)
MP4Box -add "${CONVFILE}#1" -add "${CONVFILE}#2" -set-meta meta:tk=1 -new "${PROCFILE}"
When I then try to parse the file via mp4parse::read_mp4(&mut file).unwrap() I get thread 'main' panicked at 'calledResult::unwrap()on anErrvalue: InvalidData(CheckParserStateErr)'
Can you please have a look at this? In the gpac area I already tried to investigate what happens, but I have to confess that I'm not an expert obviously ;). -> https://github.com/gpac/gpac/issues/2603
