#7662: When using video filter fps, provide an option to retain actual pts, and pts_time for frames -----------------------------------+-------------------------------------- Reporter: vishal733 | Type: defect Status: new | Priority: normal Component: avfilter | Version: git-master Keywords: fps | Blocked By: Blocking: | Reproduced by developer: 1 Analyzed by developer: 1 | -----------------------------------+-------------------------------------- Summary of the bug: How to reproduce: {{{ % ffmpeg -i input -filter_complex "showinfo,fps=20,showinfo" out_%03d.png ffmpeg version: master (current head: ed3b64402ef770097f81e4f1e17f1fca253159aa, avfilter/af_anlmdn: ignore too small values ) built on macOS }}} Output: {{{ [Parsed_showinfo_0 @ 0x...] n: 0 pts: 0 pts_time:0 pos: 93846 ...

[Parsed_showinfo_2 @ 0x...] n: 1 pts: 1 pts_time:0.05 pos: 95358 ... }}} In the output, showinfo_0 refers to timestamps before action of fps. and showinfo_2 refers to timestamps after action of fps. Clearly you can see that pts is artificially alterered for frames obtained after fps filter. (Ex: pts of frame at pos 95358 is altered from 0.0666667 to 0.05) Can we not have a pts_bypass mode which allows to have the pts of frames unaltered. This will be really useful for applications using ffmpeg to decode frames, and then having accurate back-correspondence. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7662> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

This can help recover the original file by undelete, if it was accidentaly deleted by specifying wrong ffmpeg parameters. Ffmpeg deleted an important video and it cannot be recovered because it truncated the file, not deleted it before. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7667> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#7242(avfilter:new): zoompan filter variables 'in' and 'on' start at 2, 1 instead of at 0
by FFmpeg 10 Jan '19

#7242: zoompan filter variables 'in' and 'on' start at 2, 1 instead of at 0 ----------------------------------+-------------------------------------- Reporter: jdlh | Type: defect Status: new | Priority: normal Component: avfilter | Version: git-master Keywords: zoompan | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+-------------------------------------- '''Summary of the bug''': The video filter '''zoompan''' creates variables '''in''' and '''on''' for use in expressions. They are described as the "input frame count" and "output frame count" respectively. When '''zoompan''' filters the first frame, '''in''' is 2, and '''on''' is 1. These are non-intuitive values. I expect them both to be 0 for the first frame. '''How to reproduce''': Use '''[https://ffmpeg.org/ffmpeg-all.html#zoompan zoompan]''' filter, with expressions which examine the '''in''' and '''on''' values for each frame. Two invocations demonstrate this. Full invocations below and `-report` logs below. [1] Comparing '''zoompan:in''' and '''zoompan:on''' with '''crop:n''' {{{ ./ffmpeg -report -v +repeat -to 0.3 -i fate-suite/h264/interlaced_crop.mp4 -an \ -vf "crop=x=print(1234000+n)*0,zoompan=d=1:s=qhd:zoom=print(2718000+in)*0+print(3142000+on)*0+1" \ -f mp4 -y /dev/null ...[omitted here for brevity] ... 1234000.000000 1234000.000000 2718002.000000 3142001.000000 ...[omitted here for brevity] ... }}} [2] Same problem with '''zoompan:in''' and '''zoompan:on''' even if no other filters {{{ ffmpeg started on 2018-06-02 at 23:41:59 Report written to "ffmpeg-20180602-234159.log" Command line: ./ffmpeg -report -v +repeat -to 0.3 -i fate-suite/h264/interlaced_crop.mp4 -an \ -vf "zoompan=d=1:s=qhd:zoom=print(2718000+in)*0+print(3142000+on)*0+1" \ -f mp4 -y /dev/null ...[omitted here for brevity] ... 2718002.000000 3142001.000000 ...[omitted here for brevity] ... }}} '''Expected behaviour''' I expect '''in''' and '''on''' to have the value 0 when the filter operates on the first input frame and generates the first output frame. This is consistent with how the '''n''' variable behaves with many other video filters, e.g. '''crop''', '''drawtext''', etc. When the filter operates on subsequent output frames for a given input frame, I expect '''in''' to remain at the same value, and '''on''' to increment by 1 for each output frame. When the filter operates on the next input frame, I expect both '''in''' and '''on''' to increment by 1 relative to their values for the final output frame of the previous input frame. '''on''' should not reset to zero; the '''zoompan:duration''' variable already has this behaviour. I expect the documentation for '''zoompan''''s '''in''' and '''on''' variables to be clearer and more consistent with the documentation for the '''n''' variable in other video filters, e.g. '''crop'''. For example: '''in''': The number of the input frame, starting from 0. It keeps the same value as the filter generates successive output frames for the same input frame. '''on''': The number of the output frame, starting from 0. It increments as the filter generates successive output frames for a given input frame, and increments again when the filter moves to first output frame for the next input frame.

#7056(undetermined:new): Make ffmpeg to automatically convert audio sample format to floating point before apllying filters

#7056: Make ffmpeg to automatically convert audio sample format to floating point before apllying filters -------------------------------------+------------------------------------- Reporter: Rollinnn | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: git- Keywords: | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Summary of the bug: It seems that currently, if source file has sample format 16 or 24 bit fixed point, then ffmpeg process it also in fixed point format. With some processing this can result in audible clipping, even if "alimiter" filter is used in the end of filter chain. So it is needed to manually change sample format with "aformat=sample_fmts=flt" in the beginning if filters chain to be able to prevent clipping. == Suggestion is to convert sample format to floating point automatically before applying filters. == Example. If attached flac file is processed with command {{{ ffmpeg -i input.flac -af "pan=stereo|FL=0.707*FC+FL+0.707*BL+0.707*SL+0.5*BC|FR=0.707*FC+FR+0.707*BR+0.707*SR+0.5*BC, alimiter=attack=0.1" output.flac }}} then resulted file contains obvious and audible clipping regardless alimiter was used But if "aformat=sample_fmts=flt" is added to beginning of filter chain, so command is {{{ ffmpeg -i input.flac -af "aformat=sample_fmts=flt, pan=stereo|FL=0.707*FC+FL+0.707*BL+0.707*SL+0.5*BC|FR=0.707*FC+FR+0.707*BR+0.707*SR+0.5*BC, alimiter=attack=0.1" output.flac }}} there is no clipping in resulted file, because alimiter succesfully supress it. Yes, i know that i can simlpy use -ac 2 for downmixing. ffmpeg is static build from Zeranoe. How to reproduce: Once again This command results in file with no clipping {{{ ffmpeg -i C:\000\sample_8channels_16bit.flac -af "aformat=sample_fmts=flt, pan=stereo|FL=0.707*FC+FL+0.707*BL+0.707*SL+0.5*BC|FR=0.707*FC+FR+0.707*BR+0.707*SR+0.5*BC, alimiter=attack=0.1" C:\000\downmixed.flac ffmpeg version N-90173-gfa0c9d69d3 Copyright (c) 2000-2018 the FFmpeg developers built with gcc 7.3.0 (GCC) configuration: --enable-gpl --enable-version3 --enable-sdl2 --enable- bzlib --enable-fontconfig --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libfreetype --enable-libmp3lame --enable- libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libtheora --enable-libtwolame --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libzimg --enable-lzma --enable-zlib --enable-gmp --enable- libvidstab --enable-libvorbis --enable-libvo-amrwbenc --enable-libmysofa --enable-libspeex --enable-libxvid --enable-libmfx --enable-amf --enable- cuda --enable-cuvid --enable-d3d11va --enable-nvenc --enable-dxva2 --enable-avisynth libavutil 56. 7.101 / 56. 7.101 libavcodec 58. 13.100 / 58. 13.100 libavformat 58. 10.100 / 58. 10.100 libavdevice 58. 2.100 / 58. 2.100 libavfilter 7. 12.100 / 7. 12.100 libswscale 5. 0.101 / 5. 0.101 libswresample 3. 0.101 / 3. 0.101 libpostproc 55. 0.100 / 55. 0.100 Input #0, flac, from 'C:\000\sample_8channels_16bit.flac': Duration: 00:00:11.04, start: 0.000000, bitrate: 2828 kb/s Stream #0:0: Audio: flac, 48000 Hz, 7.1, s16 Stream mapping: Stream #0:0 -> #0:0 (flac (native) -> flac (native)) Press [q] to stop, [?] for help [flac @ 006dacc0] encoding as 24 bits-per-sample Output #0, flac, to 'C:\000\downmixed.flac': Metadata: encoder : Lavf58.10.100 Stream #0:0: Audio: flac, 48000 Hz, stereo, s32 (24 bit), 128 kb/s Metadata: encoder : Lavc58.13.100 flac size= 2315kB time=00:00:11.04 bitrate=1717.9kbits/s speed=100x video:0kB audio:2307kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.350835% }}} And this command results in file with audible clipping: {{{ C:\Users\Андрей>ffmpeg -i C:\000\sample_8channels_16bit.flac -af "pan=stereo|FL=0.707*FC+FL+0.707*BL+0.707*SL+0.5*BC|FR=0.707*FC+FR+0.707*BR+0.707*SR+0.5*BC, alimiter=attack=0.1" C:\000\downmixed.flac ffmpeg version N-90173-gfa0c9d69d3 Copyright (c) 2000-2018 the FFmpeg developers built with gcc 7.3.0 (GCC) configuration: --enable-gpl --enable-version3 --enable-sdl2 --enable- bzlib --enable-fontconfig --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libfreetype --enable-libmp3lame --enable- libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libtheora --enable-libtwolame --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libzimg --enable-lzma --enable-zlib --enable-gmp --enable- libvidstab --enable-libvorbis --enable-libvo-amrwbenc --enable-libmysofa --enable-libspeex --enable-libxvid --enable-libmfx --enable-amf --enable- cuda --enable-cuvid --enable-d3d11va --enable-nvenc --enable-dxva2 --enable-avisynth libavutil 56. 7.101 / 56. 7.101 libavcodec 58. 13.100 / 58. 13.100 libavformat 58. 10.100 / 58. 10.100 libavdevice 58. 2.100 / 58. 2.100 libavfilter 7. 12.100 / 7. 12.100 libswscale 5. 0.101 / 5. 0.101 libswresample 3. 0.101 / 3. 0.101 libpostproc 55. 0.100 / 55. 0.100 Input #0, flac, from 'C:\000\sample_8channels_16bit.flac': Duration: 00:00:11.04, start: 0.000000, bitrate: 2828 kb/s Stream #0:0: Audio: flac, 48000 Hz, 7.1, s16 Stream mapping: Stream #0:0 -> #0:0 (flac (native) -> flac (native)) Press [q] to stop, [?] for help [flac @ 0487acc0] encoding as 24 bits-per-sample Output #0, flac, to 'C:\000\downmixed.flac': Metadata: encoder : Lavf58.10.100 Stream #0:0: Audio: flac, 48000 Hz, stereo, s32 (24 bit), 128 kb/s Metadata: encoder : Lavc58.13.100 flac size= 1286kB time=00:00:11.04 bitrate= 954.5kbits/s speed= 69x video:0kB audio:1278kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.633161% }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/7056> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
