Hi, I want to split a file by file size but as I can not find that option I thought of doing it by calculating the size using the bitrates. The problem is that when I split a file with the command line tool i receive different bitrates. I use this code to split the file:
*ffmpeg -i test.mp4 -ss 00:00:00 -to 00:20:00 -c copy test_output.mp4* and this is my result: *D:\Desktop\ffmpeg\ffmpeg\bin>ffmpeg -i test.mp4 -ss 00:00:00 -to 00:20:00 -c copy test_output.mp4ffmpeg version git-2019-10-13-4f4334b Copyright (c) 2000-2019 the FFmpeg developers built with gcc 9.2.1 (GCC) 20191010 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. 35.100 / 56. 35.100 libavcodec 58. 59.102 / 58. 59.102 libavformat 58. 33.100 / 58. 33.100 libavdevice 58. 9.100 / 58. 9.100 libavfilter 7. 62.100 / 7. 62.100 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 libpostproc 55. 6.100 / 55. 6.100Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mp4': Metadata: major_brand : mp42 minor_version : 0 compatible_brands: isommp42 creation_time : 2019-03-13T11:57:44.000000Z Duration: 00:01:28.49, start: 0.000000, bitrate: 608 kb/s Stream #0:0(und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv, bt709), 1280x720 [SAR 1:1 DAR 16:9], 477 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc (default) Metadata: creation_time : 2019-03-13T11:57:44.000000Z handler_name : ISO Media file produced by Google Inc.
