As for the filename, I used a bash variable, and it worked. I should have thought about it earlier. I haven't found yet how to keep the bitrate and size, and still have to add delay for the sound.
I tried to play back the file on another machine (Windows this time), and it doesn't work. It stays on the first part of the video, ignoring the rest, and giving errors when trying to fast forward: ./ffmpeg-20181106-d96ae9d-win64-static/bin/ffplay.exe third-HDMI-input-20190912.182417486.mkv ffplay version N-94455-g01994c93db Copyright (c) 2003-2019 the FFmpeg developers built with gcc 9.1.1 (GCC) 20190716 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-amf --enable-ffnvcodec --enable-cuvid --enable-d3d11va --enable-nvenc --enable-nvdec --enable-dxva2 --enable-avisynth --enable-libopenmpt libavutil 56. 33.100 / 56. 33.100 libavcodec 58. 55.100 / 58. 55.100 libavformat 58. 30.100 / 58. 30.100 libavdevice 58. 9.100 / 58. 9.100 libavfilter 7. 58.100 / 7. 58.100 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 libpostproc 55. 6.100 / 55. 6.100 Input #0, flv, from 'third-HDMI-input-20190912.182417486.mkv': Metadata: encoder : Lavf58.29.100 Duration: 00:00:00.00, start: 0.000000, bitrate: N/A Stream #0:0: Video: h264 (High), yuv420p(progressive), 1920x1080, 100 tbr, 1k tbn Stream #0:1: Audio: mp3, 48000 Hz, stereo, fltp, 128 kb/s SDL_OpenAudio (2 channels, 48000 Hz): WASAPI can't initialize audio client: CoInitialize n’a pas été appelé.
