Andrew, Your changes + the new Intra... will be checked in later today (or soon). I tested all of them and they all worked but you know more about it then we do.
Unfortunately, not much (just was looking at checkboxes in Avidemux settings and tried to upscale verysmall video - http://samples.mplayerhq.hu/MPEG1/ where difference in file size was obvious. I also tried to create two new profiles mpeg1.mpeg and mpeg2.mpeg with those recommended settings in them, and mpeg1_mp2.mpeg as audio file (so you can mux mpeg1 streams with sound) - but not sure how useful they can be? I also tried to create h264 flv, but swftool failed to merge it into swf, and I don't know any other open-source tool for merging/wrapping flv into swf https://en.wikipedia.org/wiki/Flash_Video https://stackoverflow.com/questions/45484607/how-to-properly-wrap-h264-into-... Those two somewhat confusing, _I think_ flv muxer in ffmpeg can mux h264 in flv (for example for uploading to youtube/etc), but how useful this can be in real-life I don't know .... https://trac.ffmpeg.org/wiki/EncodingForStreamingSites --- Encoding a file for streaming If your computer is too slow to encode the file on-the-fly like the example above then you can re-encode it first: $ ffmpeg -i input.mkv -c:v libx264 -preset medium -b:v 3000k -maxrate 3000k -bufsize 6000k \ -vf "scale=1280:-1,format=yuv420p" -g 50 -c:a aac -b:a 128k -ac 2 -ar 44100 file.flv Then stream copy it to the streaming service: $ ffmpeg -re -i file.flv -c copy -f flv rtmp://live.twitch.tv/app/<stream key> ----
I also tried AVC-Intra-100 encoding - slow on my machine, but apparently
produces mp4?
Yes, it produced mp4 and it was not slow on my laptop but I ran a very small file without audio.
Of course audio better to be PCM .... Can anyone check if this file edi(t)able by other video editors?
I do not have MLV or any other video editor to test. Maybe Andrea can after we check it in?
