Hi, I wanted to know if we can feed the output of an encode operation to a "filter_complex" with a command like: "ffmpeg -i input.mp4 -c:v libx264 -b:v 10000k "[encoder-output-1]" \ -c:v libx264 -b:v 5000k "[encoder-output-2]" \ -c:v libx264 -b:v 2000k "[encoder-output-3]" \ -filter_complex "[encoder-output-1][0:v]psnr" -f null - \ -filter_complex "[encoder-output-2][0:v]psnr" -f null -\ -filter_complex "[encoder-output-3][0:v]psnr" -f null - "
If we can do something like this, I wanted to know how I need to name the output pad of the encoder, so that I can reference/map it in the filter_complex If not, please let me know what is the easiest way to achieve something like this. Note: 1. I want to use filter_complex here, rather than use the psnr x264 option, as I will be replacing the x264 encoder with something else (which doesn't support PSNR computation) 2. I don't want to dump the output of the encoder to a file and then feed it to another ffmpeg pipeline to compute psnr 3. I want to avoid using pipes, as I will be generating multiple bitrate streams from the encoder Thanks, Best Regards, Nitish This is confidential Ittiam property. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
