#6843: PGS subtitle encoder -------------------------------------+------------------------------------- Reporter: Sami32 | Type: task Status: new | Priority: wish Component: avcodec | Version: Keywords: PGS encoder | unspecified Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- With a full color/alpha palette and without the need to use -canvas_size option, PGS should be a good alternative to the already existing DVBSUB picture encoder. Since converting it to DVDSUB is blurred, ugly by now, [PGS=http://blog.thescorpius.com/index.php/2017/07/15/presentation- graphic-stream-sup-files-bluray-subtitle-format/] could be an alternative in case #6835 could not be solved. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6843> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#7111: AAC profiles MPEG-2 and MPEG-4 are not displayed distincly -------------------------------------+------------------------------------- Reporter: Sami32 | Type: Status: new | enhancement Component: avcodec | Priority: normal Keywords: aac | Version: git- profiles | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Example: Audio: aac (LC) Why not also display their profile ID after, as do MediaInfo? From the FFmpeg code. FF_PROFILE_MPEG2_AAC_LOW 128 FF_PROFILE_AAC_LOW 1 The point is to be able to use FFmpeg only without the need of MediaInfo or any other tool, as some old renderers only support the MPEG-2 profiles. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7111> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#7114(avcodec:new): Add options to set some AVCodecContext's field

#7114: Add options to set some AVCodecContext's field -----------------------------------+--------------------------------------- Reporter: jyavenard | Type: enhancement Status: new | Priority: normal Component: avcodec | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+--------------------------------------- There's currently no options to set the following members of AVCodecContext via AVOptions, which are ABI dependent. extradata extradata_size opaque get_format codec_id that list isn't exhaustive obviously (but that's what we use today) which means you must hope that the binary definition of AVCodecContext hasn't changed between the header you use and the library you're linking to. One example would be if libavcodec was built with FF_API_CODEC_NAME set, all structure field would be shifted by 32 bytes. Seeing that the ABI of AVCodecContext isn't fixed, one can't guarantee the outcome of using an external libavcodec shared lib. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7114> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
