#7965(ffmpeg:new): Support for HEVC with Alpha

#7965: Support for HEVC with Alpha -----------------------------------+--------------------------------------- Reporter: leemartin | Type: enhancement Status: new | Priority: normal Component: ffmpeg | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+--------------------------------------- At WWDC this year, Apple introduced support for HEVC with Alpha to both their app and browser platforms. You can find their talk on the subject here: https://developer.apple.com/videos/play/wwdc2019/506 I'm an amateur at FFmpeg but I went down a rabbit hole today, trying to create a video in this new format using the latest version of FFmpeg. I took a rather simple approach of using ffprobe on one of their example video files (found in the resources on the link above) to get a profile and attempting to tune an ffmpeg encoding command to fit the same profile. While the following command does recreate the profile, it does not retain the transparency of the source prores .mov file. {{{ % ffmpeg -i puppets_with_alpha_prores.mov -c:v libx265 -tag:v hvc1 -pix_fmt yuv420p -colorspace bt709 -color_primaries bt709 -color_trc bt709 puppets_with_alpha_hevc.mov }}} Apple is pretty clear about how they are achieving this encoding in their talk and examples. Naturally, I didn't follow anything they said and simply tried to hack a solution. So I'm wondering if this is something FFmpeg can do or would be able to support in the future? Thanks for the help! -- Ticket URL: <https://trac.ffmpeg.org/ticket/7965> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#7756(avcodec:new): add mastering display color volume and content light level information to hevc_metadata bitstream filter

#7756: add mastering display color volume and content light level information to hevc_metadata bitstream filter ---------------------------------+--------------------------------------- Reporter: sneaker | Type: enhancement Status: new | Priority: wish Component: avcodec | Version: git-master Keywords: hevc | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+--------------------------------------- It's currently already possible to use the "[https://ffmpeg.org/ffmpeg- bitstream-filters.html#hevc_005fmetadata hevc_metadata" bitstream filter] (-bsf:v hevc_metadata) to add or change colour_primaries, transfer_characteristics and matrix_coefficients of a given HEVC bitstream losslessly. The only things missing to allow ffmpeg to properly set HDR metadata on existing HEVC streams would be to set SMPTE ST 2086 Mastering display color volume SEI and Content light level information SEI message (MaxCLL and MaxFALL). This is useful because not all encoders currently allow setting those as well as in the case you forgot setting them during encode time. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7756> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#11390(ffmpeg:new): av1_nvenc output frames sometimes cannot be decoded
by FFmpeg 15 Aug '25

#11390: av1_nvenc output frames sometimes cannot be decoded -----------------------------------+-------------------------------------- Reporter: nikomo | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: git-master Keywords: av1_nvenc | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+-------------------------------------- Summary of the bug: av1_nvenc output with some inputs will occasionally produce unplayable files. Attached files result in latest stable VLC decoding blocks, but not any frames. Windows's built-in Media Player plays back sample fine, but with full file as input, audio in output file will not be played back in Media Player but video will, while VLC will play audio but not video.

#11012(avformat:new): APNG decoder incorrectly assumes fcTL chunk must be immediately followed by fdAT or IDAT

#11012: APNG decoder incorrectly assumes fcTL chunk must be immediately followed by fdAT or IDAT ----------------------------------+--------------------------------------- Reporter: tobbez | Type: defect Status: new | Priority: normal Component: avformat | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- The APNG decoder (more specifically `apng_read_packet` in libavformat/apngdec.c) incorrectly assumes an `fcTL` chunk must be ''immediately'' followed by either an `fdAT` or an `IDAT` chunk. In addition, when the `fdAT`/`IDAT` check fails, the input stream is not rewinded to the start of the chunk that follows the `fcTL` chunk, causing misleading log messages: "tag=ware (0x65726177) len=1399809652" in the output below ought to be "tag=tEXt (0x74584574) len=16". An example file can be created using exiftool on an existing APNG file (`exiftool -Software=example apng.png`). This produces a file where the first `fcTL` chunk is followed by a `tEXt` chunk. Such an example will be attached.

However if the time changes e.g. segments generated from two video files, ffmpeg got error 'Non- monotonous DTS in output stream 0:1;'. According to the HLS documentation, EXT-X-DISCONTINUITY should be used when time sequence changes. (https://tools.ietf.org/html/draft-pantos- http-live-streaming-13#section-3.4.11) But I still got the same error after I added that tag to the m3u8 file. Look at hls.c file in libavformat, it doesn't handle EXT-X-DISCONTINUITY tag.
