#10041: Problem with exposure filter -------------------------------------+------------------------------------- Reporter: Michael | Type: defect Koch | Status: new | Priority: normal Component: avfilter | Version: git- | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Make a 10-bit grayscale test image: ffmpeg -f lavfi -i color=black:s=16x64,format=gray10le -lavfi geq=lum='X+16*Y',format=gray10le,datascope=s=640x768:mode=color2:format=hex -frames 1 -y test.png Apply the exposure filter, followed by a limiter: ffmpeg -i test.png -vf format=rgb48,exposure=exposure=1:black=0.4,limiter -y out.png exposure=1 should be equivalent to a factor 2, but the amplification in the output image is much stronger. It becomes even worse if black=0.5 is used, then the output image contains only black or white pixels, that's infinite amplification. Either something is wrong, or I did misunderstand what the filter is supposed to do. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10041> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#9461(avfilter:new): Showpectrum scale doesn't work anymore

#9461: Showpectrum scale doesn't work anymore -----------------------------------+-------------------------------------- Reporter: RKleinert | Type: defect Status: new | Priority: normal Component: avfilter | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+-------------------------------------- == Summary of the bug: == In https://trac.ffmpeg.org/ticket/8919 I had adressed a bug that would mess up the scaling of the frequency-axis in showspectrum() and showspectrumpic() when choosing a starting-frequency that is not zero. This bug is now supposedly fixed. Now after the "fix" both functions won't work anymore at all when used with my prevousily used arguments. Especialy defining an output size (which is crucial) seems to lead to a never ending loop where ffmepg doesn't get anywhere. My batch-script doesn't end and no output is written. Secondly I noticed, that the argument "legend" doesn't default to 0 (as it states in the doc) but to 1 - so the legend and axes are always enabled if not actively disabled. == How to reproduce: == {{{ #!div style="font-size: 80%" The Sample Code: ffmpeg -i input.wav -filter_complex "showspectrumpic=size=700x400:mode=combined:color=rainbow:scale=sqrt:fscale=log:legend=1:start=500:stop=20000" output.png leads into an endless loop. Whereas the code without the size-argument: ffmpeg -i input.wav -filter_complex "showspectrumpic=mode=combined:color=rainbow:scale=sqrt:fscale=log:legend=1:start=500:stop=20000" output.png does the trick (although it takes quite some time to run) }}} {{{ ffmpeg version 2021-10-18-git-d04c005021-full built from gyan.dev }}} I supplied the input.wav file which is a test-sample with a 1kHz-Sinewave -- Ticket URL: <https://trac.ffmpeg.org/ticket/9461> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10077: ffmpeg : #EXT-X-INDEPENDENT-SEGMENTS not added when audio file ------------------------------------+------------------------------------- Reporter: xavierlaff | Type: defect Status: new | Priority: important Component: ffmpeg | Version: 5.1.2 Keywords: HLS | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ------------------------------------+------------------------------------- I noticed in the code that only when the file contains video "#EXT-X -INDEPENDENT-SEGMENTS" is appended with the hls_flag Independent_segments argument. (hlsenc.c file, line 1601) I think it's a mistake because in the HLS rfc nothing indicates that only the video is concerned '''Reproduce:''' ffmpeg -i audio_file.mp4 -codec copy -f hls '''-hls_flags independent_segments''' -master_pl_name master.m3u8 -hls_segment_type mpegts -hls_playlist_type vod "playlist.m3u8" -- Ticket URL: <https://trac.ffmpeg.org/ticket/10077> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
