FFMPEG supports simultaneous creating of multiple outputs. It could be highly useful in HLS and DASH creation:

Code: Select all

ffmpeg.exe -i test.mp4
-s 1280x720 -f segment -segment_time 1 -segment_list "1000.m3u8" -segment_format mpegts "1000_%%05d.ts" -c:a aac -ar 48000 -b:a 256k -b:v 1000k -c:v libx264 -profile:v high -level 4.2 -preset medium -flags -global_header -movflags +faststart test1280x720.mp4
-s 854x480 -f segment -segment_time 1 -segment_list "450.m3u8" -segment_format mpegts "450_%%05d.ts" -c:a aac -ar 48000 -b:a 128k -b:v 450k -c:v libx264 -profile:v high -level 4.2 -preset medium -flags -global_header -movflags +faststart test854x480.mp4
-s 640x360 -f segment -segment_time 1 -segment_list "250.m3u8" -segment_format mpegts "250_%%05d.ts" -c:a aac -ar 48000 -b:a 64k -b:v 250k -c:v libx264 -profile:v high -level 4.2 -preset medium -flags -global_header -movflags +faststart test640x360.mp4
Now we can use (I suppose) "Custom FFmpeg" processor, but it does not have all those bells and whistles (in the finest sense of the word) of "H.264" processor.

I can see why that would be useful but it takes a lot of rewriting of the node and that that wont be focus now. But I will note the request. Thanks! :-)
