#8588: Palettegen adds one color on transparent input -------------------------------------+------------------------------------- Reporter: RedError | Type: defect Status: new | Priority: normal Component: avfilter | Version: git- Keywords: palettegen | master color transparency gif png alpha | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: [https://github.com/FFmpeg/FFmpeg/blob/master/libavfilter/vf_palettegen.c palettegen] from a transparent gif, png, adds the invisible transparency color to the palette as a visible color, with no relation to the one selected with the transparency_color option. On transparent PNG, it will use the rgb value of the transparent areas. On transparent GIF, it will always add white. None of the available [https://ffmpeg.org/ffmpeg-filters.html#palettegen-1 options] seem to change that. How to reproduce: {{{ ffmpeg -i "transparent.gif" -vf palettegen "palette.png" -y }}} Of course, using that palette with paletteuse will use the added color in the result, as paletteuse has no way of knowing that it was actually a transparent color. {{{ ffmpeg -i "target.png" -i "palette.png" -lavfi paletteuse=dither=0 "target_merged.gif" }}} This will randomly add one color where there shouldn't be one. -- Ticket URL: <https://trac.ffmpeg.org/ticket/8588> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#9950: No docs for paletteuse filter option "dither=none" -------------------------------------+------------------------------------- Reporter: jason | Type: defect Status: new | Priority: normal Component: | Version: documentation | unspecified Keywords: filters | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- The [https://ffmpeg.org/ffmpeg-filters.html#paletteuse docs for paletteuse] list "bayer", "heckbert", "floyd_steinberg", "sierra2", and "sierra2_4a" as acceptable values for "dither", with no documented option for disabling dithering entirely. However, the filter appears to accept "none" as an option to disable dithering, at least in: - Whatever version [https://video.stackexchange.com/a/32666 the author of this answer] was using in Nov 2020, as well as the author of the question there, and - My version: 4.3.2-2021-02-27-full_build-www.gyan.dev (I didn't test on others). It should probably be documented. However, I'm not sure if this is a documentation error vs. "none" not being a stable long-term option. Does anybody know what version "dither=none" started being valid with, and whether or not it's intended to continue working in the foreseeable future? If it's an unstable or temporary feature, then it might not actually be a documentation error. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9950> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10908(avformat:new): avformat/mpegtsenc: mpegts_check_bitstream broken since 8559cce3c37b (wrong operator precedence)

#10908: avformat/mpegtsenc: mpegts_check_bitstream broken since 8559cce3c37b (wrong operator precedence) -------------------------------------+------------------------------------- Reporter: Sebastian | Type: defect Meyer | Status: new | Priority: normal Component: avformat | Version: git- | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- **Summary of the bug:** Commit [https://github.com/FFmpeg/FFmpeg/commit/8559cce3c37b08e37fd208b8895a87adb88… 8559cce3c37b] refactored mpegtsenc's `mpegts_check_bitstream` function and added a codec-id lookup table instead of checking each codec-id individually. In the process, a `uint8_t` bitmask was applied to the stream's `st->codecpar->extradata[0]` which was intended to be checked against the lookup table's `value` field. However, the commit author and the reviewers made a mistake and didn't notice the incorrect operator precedence of the bitwise-and and equality comparison. Beginning from this commit until today's HEAD commit on the master branch, muxing MPEG-TS fails for certain inputs. **This issue was originally noticed here:** https://github.com/streamlink/streamlink/issues/5876 **How to reproduce:** In the issue thread linked above, there's sample data of two MPEG-TS streams, one video and one audio stream. Remuxing into one MPEG-TS stream fails due to this bug. Builds of earlier commits work fine. https://github.com/streamlink/streamlink/files/14537316/5876.zip The error messages are this: {{{ [mpegts @ 0x6392afb61240] h264 bitstream error, startcode missing, size 100902 data 00018A22 [mpegts @ 0x6392afb61240] h264 bitstream error, startcode missing, size 539 data 00000217 [mpegts @ 0x6392afb61240] h264 bitstream error, startcode missing, size 165 data 000000A1 ... }}} Since I'm not familiar with mailing lists and since I didn't find the bug myself, I'm not going to send a patch. The person who found this bug in the linked issue thread apparently wanted to submit a patch, but hasn't responded since, so I decided to open this bug report instead. Maybe some of the responsible devs want to have a look at this again anyway. Thanks. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10908> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10904: Slow nvenc encodes affect h264 and hevc with certain videos --------------------------------------+---------------------------------- Reporter: nikkoaki | Type: defect Status: new | Priority: normal Component: undetermined | Version: 6.1 Keywords: nvenc | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | --------------------------------------+---------------------------------- Summary of the bug: Been using nvenc for encoding for some time and never had problems. Usually always got 100+ fps converting a 4K video to a lower bit rate 4K one. Lately i tried the same on a video shot with my latest phone and noticed that i barely get 30fps. First i was trying with handbrake but tried just ffmpeg to rule out the other project and it behaves the same. I also shot with a lower bit rate to match my old phone but again, it behaves the same. ffmpeg output from a video from my old phone: {{{ Metadata: major_brand : mp42 minor_version : 0 compatible_brands: isommp42 creation_time : 2021-05-12T11:49:14.000000Z com.android.version: 8.1.0 Duration: 00:01:13.56, start: 0.000000, bitrate: 35577 kb/s Stream #0:0[0x1](eng): Video: hevc (Main) (hvc1 / 0x31637668), yuvj420p(pc, smpte170m), 3840x2160, 35408 kb/s, SAR 1:1 DAR 16:9, 29.97 fps, 30 tbr, 90k tbn (default) Metadata: creation_time : 2021-05-12T11:49:14.000000Z handler_name : VideoHandle vendor_id : [0][0][0][0] Stream #0:1[0x2](eng): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 189 kb/s (default) Metadata: creation_time : 2021-05-12T11:49:14.000000Z handler_name : SoundHandle vendor_id : [0][0][0][0] File 'output.mp4' already exists.
