#8493: Allow setting mastering display metadata and content light level information in Quitcktime files -----------------------------------+--------------------------------------- Reporter: hubner | Type: enhancement Status: new | Priority: normal Component: ffmpeg | Version: git-master Keywords: quicktime | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+--------------------------------------- I'm trying encode a Quicktime file with HDR metadata. I was able to set the color space, the color primaries, and the color transfer characteristics but it is not possible to set the mastering display metadata and the content light level information. I had a look at the code and it seems that in the mov decoder the information is already parsed from the file. However, in the mov encoder the atoms for these metadata are not written yet. In #7756 a similar enhancement is requested but for HEVC instead of Quicktime. -- Ticket URL: <https://trac.ffmpeg.org/ticket/8493> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10899: signed integer overflow at 'libavformat/avidec.c:1699' -------------------------------------+------------------------------------- Reporter: Sean | Type: defect McGovern | Status: new | Priority: normal Component: avfilter | Version: git- | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: Many FATE tests trigger signed integer overflow on big-endian FATE nodes such as 'ppc-linux-gcc-13.2-ubsan-altivec-qemu'. The output looks similar to the following: {{{ src/libavformat/avidec.c:1699:55: runtime error: signed integer overflow: 9223372036854775807 + 1 cannot be represented in type 'long long int' }}} As the PowerPC FATE nodes are currently the only big-endian representation we have, it is unclear if this is only particular to this configuration. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10899> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
