#3643: XYZ to RGB color space -------------------------------------+------------------------------------- Reporter: tteam | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: Keywords: more XYZ to | unspecified RGB matrix | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: XYZ to RGB colorspace conversion use only sRGB matrix and sometimes the conversion is deffected in red channel and the picture is dark. Hi all! Is it possible to add more color space matrix (in option) to XYZ to RGB conversion? Because the FFMPEG use only one matrix (sRGB) but lots of available, and best if the user can choose one. Because the problem is: sometimes the conversion is deffected the red is much more and the picture is dark. If possible please add some from this list. The default is the sRGB but optional the others.

#7337(undetermined:new): FFmpeg not recognizing WebVTT subtitle stream from HLS playlist

#7337: FFmpeg not recognizing WebVTT subtitle stream from HLS playlist -------------------------------------+------------------------------------- Reporter: newsfanatic | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: | Blocked By: WebVTT,HLS,m3u8,playlist,subtitles | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When trying to ingest an HLS playlist from an m3u8 endpoint online to an mkv container, the subtitle stream is not being picked up at all. I can confirm that all other audio and video streams are being recognized, whilst the subtitle stream is not. I can also confirm that WebVTT is listed as a supported subtitle codec from ```ffmpeg -codecs```. Specifying ```-map 0``` also fails to pick up the subtitle stream. Am I just forgetting a flag or option?

#9285(avcodec:new): Excessive GPU memory usage with nvdec hwaccel

#9285: Excessive GPU memory usage with nvdec hwaccel -------------------------------------+------------------------------------- Reporter: Ridley | Type: defect Combs | Status: new | Priority: normal Component: avcodec | Version: Keywords: nvdec | unspecified nvidia | Blocked By: Blocking: | Reproduced by developer: 1 Analyzed by developer: 1 | -------------------------------------+------------------------------------- When decoding video using the CUDA hwaccel, `ff_nvdec_decode_init()` sets both `ulNumDecodeSurfaces` and `ulNumOutputSurfaces` to `frames_ctx->initial_pool_size`, which in turn is set by `ff_nvdec_decode_init` to `dpb_size + 2`, which in turn has 3 added by `ff_decode_get_hw_frames_ctx()` and `extra_hw_frames` + `thread_count` added by `avcodec_get_hw_frames_parameters`. This is excessive. Only `ulNumDecodeSurfaces` needs additional frames based on thread count (the output surfaces are only used in `nvdec_retrieve_data`, which runs on the consumer's single thread), while only `ulNumOutputSurfaces` needs the 3 additional output frames from `ff_decode_get_hw_frames_ctx()` or the ones from `extra_hw_frames` (the decode surfaces are never exposed to the consumer). I'm not sure what the best way to handle this is. Maybe nvdec should ignore what the generic code sets `initial_pool_size` to altogether and instead calculate its buffer counts internally, duplicating the generic code's behavior only where appropriate? The `initial_pool_size` value seems to be designed for systems where the decoder's internal buffered frames are returned directly to the user, but that's not the case here. Additionally, it doesn't seem like multithreading in CUDA actually serves any purpose; I see no performance gain when using multiple threads vs 1. Is it useful with any hardware decoder? Should we be defaulting multithreading off when using a hwaccel, or forcing it off unless the hwaccel fails and software fallback occurs? This can result in some pretty hefty memory usage for no reason by default on many-core machines. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9285> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#8948: CUDA decoder fails on certain files. -------------------------------------+------------------------------------- Reporter: ericbg | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When I try to use a CUDA decoder on a specific file, I end up getting an error "Using more than 32 (42) decode surfaces might cause nvdec to fail." and then it won't use CUDA to process the file.. The number in the brackets seems to be "29 + threads"; for example, I have a 12-thread Ryzen 3600 and when I don't specify threads it says 42 (for some reason internally 'threads' is set to 13 even though I don't have that many?), when I try `-threads 4` it says 33, and when I try `-threads 3` it just works! This is where the error is from: https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/nvdec.c#L401. The problem is also file-specific; after I re-enc the file, it works just fine without any fiddling. Computer: Ryzen 3600, Nvidia 1660Ti, Windows 10 Pro N.

#6763(swscale:new): swscale: Out-of-bounds memory accesses
by FFmpeg 13 Apr '25

#6763: swscale: Out-of-bounds memory accesses ---------------------------------+--------------------------------------- Reporter: Gramner | Type: defect Status: new | Priority: normal Component: swscale | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+--------------------------------------- Many assembly functions in swscale will read past the end of their input buffers which causes segfaults and/or bus errors if the buffer happens to be located near the end of a memory page and the next page is invalid. Aligning input buffers isn't even enough for formats like RGB24 (and requiring alignment would be a bad idea anyway since it wouldn't work with memory-mapped input files for example). Using swscale with x264 CLI seems to be a fairly consistent way to trigger such out-of-bounds crashes. This command line for example will cause segfaults in ff_rgb24ToY_avx(): ./x264 -o /dev/null --input-csp rgb --input-res 512x512 <any_input_file> If asm is disabled in swscale the problem goes away. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6763> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
