#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

#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.

#9693: change of matrix cannot happen on full range ---------------------------------+-------------------------------------- Reporter: Balling | Type: defect Status: new | Priority: important Component: swscale | Version: git-master Keywords: zscale | Blocked By: Blocking: | Reproduced by developer: 1 Analyzed by developer: 0 | ---------------------------------+-------------------------------------- Summary of the bug: I have BT.709 sample that I want to do a jpeg image from, yet because std- complient jpeg is only bt.601 full range and thus the change of matrix must occur it just sees hevc video as bt.601 full range and does a no-op! Does not happen in png (remove gAMA from png). So apparently c523724c693ee031d8b5351aff6232a1f7d86876 was not enough!

#5419(avformat:new): HLS EXT-X-DISCONTINUITY tag is not supported

#5419: HLS EXT-X-DISCONTINUITY tag is not supported -----------------------------------+--------------------------------------- Reporter: xyq204101 | Type: enhancement Status: new | Priority: normal Component: avformat | Version: git-master Keywords: hls | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+--------------------------------------- Summary of the bug: I'm trying to read input from HLS and output to RTMP, this works fine if the HLS segments are all in one time sequence. 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. How to reproduce: {{{ ffmpeg -re -i http://hls-server/playlist.m3u8 -acodec copy -vcodec copy -bsf:a aac_adtstoasc -f flv rtmp://rtmp-server/app }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/5419> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10966(undetermined:new): Regression - Memory leak when muxing raw h264 streams

#10966: Regression - Memory leak when muxing raw h264 streams -------------------------------------+------------------------------------- Reporter: Francesco | Type: defect Bucciantini | Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: h264 | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When raw h264 streams (i.e raw_video.h264 files) are being muxed in a container, FFMpeg keeps allocating RAM with no clear progress until it goes into paging files on Windows or swap on Linux and then eventually crashes. How to reproduce: Step 1) Create a simple Colorbars script with Avisynth and call it "AVS Script.avs" {{{ ColorBars(1920, 1080, pixel_type="YUV422P16") }}} Step 2) Encode the colorbars with x264 to create a raw_video.h264 stream {{{ x264-10b.exe "AVS Script.avs" --preset medium --profile high422 --level 4.1 --opencl --keyint 1 --no-cabac --avcintra 100 --avcintra-flavor panasonic --deblock -1:-1 --tff --overscan show --colormatrix bt709 --range tv --log-level info --thread-input --transfer bt709 --colorprim bt709 --videoformat component --nal-hrd cbr --output-depth 10 --output-csp i422 --output "raw_video.h264" }}} Step 3) Mux the newly produced raw_video.h264 into any container you like, be it mkv or mxf or whatever {{{ ffmpeg.exe -hide_banner -i "raw_video.h264" -map 0:0 -c:v copy -f mxf "output.mxf" }}} Expected behavior: FFMpeg muxes the file in mxf or whatever container you pick. Actual behavior: FFMpeg keeps allocating RAM until it crashes with no clear progress. In the following example, I'm trying to use the newly encoded H264 stream and the audio from Avisynth on a real file to then re-encode the audio in PCM 24bit 48000Hz little endian and mux the whole thing in mxf [[Image(https://i.imgur.com/NJGfFUV.png)]] [[Image(https://i.imgur.com/jTPU3OZ.png)]] [[Image(https://i.imgur.com/LjoFkkQ.png)]] That's the latest master from today, namely N-114842-g639013aafc from the 17th of April 2024. Using version N-97504-g1128aa8 from 2020 works instead with the exact same commands, which points to a regression. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10966> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
