Hello, I have an image sequence of line drawings where the drawings change abruptly. Ffmpeg is resetting the frame numbers that I am burning in using the drawtext option every time there is an abrupt change. Here is the command I am using, and the output:
ffmpeg.exe -y -r 10 -i final-%d.png -vf "drawtext=fontfile='C\:/WINDOWS/fonts/arialbd.ttf':text=% {frame_num}:start_number=1:fontcolor=black:fontsize=15:x=10:y=10,fps=10" - pix_fmt rgb24 -c:v qtrle -r 10 test.mov ffmpeg version git-2020-02-18-ebee808 Copyright (c) 2000-2020 the FFmpeg developers built with gcc 9.2.1 (GCC) 20200122 configuration: --enable-gpl --enable-version3 --enable-sdl2 --enable- fontconfig --enable-gnutls --enable-iconv --enable-libass --enable-libdav1d -- 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-libaom --enable-libmfx --enable-ffnvcodec --enable-cuvid --enable- d3d11va --enable-nvenc --enable-nvdec --enable-dxva2 --enable-avisynth -- enable-libopenmpt --enable-amf libavutil 56. 41.100 / 56. 41.100 libavcodec 58. 70.100 / 58. 70.100 libavformat 58. 38.101 / 58. 38.101 libavdevice 58. 9.103 / 58. 9.103 libavfilter 7. 76.100 / 7. 76.100 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 libpostproc 55. 6.100 / 55. 6.100 Input #0, image2, from 'final-%d.png': Duration: 00:00:04.96, start: 0.000000, bitrate: N/A Stream #0:0: Video: png, gray(pc), 240x196 [SAR 7559:7559 DAR 60:49], 25 fps, 25 tbr, 25 tbn, 25 tbc Stream mapping: Stream #0:0 -> #0:0 (png (native) -> qtrle (native)) Press [q] to stop, [?] for help Output #0, mov, to 'test.mov': Metadata: encoder : Lavf58.38.101 Stream #0:0: Video: qtrle (rle / 0x20656C72), rgb24, 240x196 [SAR 1:1 DAR 60:49], q=2-31, 200 kb/s, 10 fps, 10240 tbn, 10 tbc Metadata: encoder : Lavc58.70.100 qtrle frame= 124 fps=0.0 q=-0.0 Lsize= 635kB time=00:00:12.30 bitrate= 422.9kbits/s dup=3 drop=0 speed=92.5x video:634kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.200005% The images start at 1 and sequentially increment. But when the image changes dramatically, the frame numbering starts over at 1 again. So out of 124 images I get 4 sequences burned in: 1-82 1-5 1-25 1-9 How can I turn off the scene detection so that it stops resetting the frame counter? Thanks. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
