FFmpeg patches.
Calculate bandwidth estimate for the hls master manifest.
This repository contains a patch for the FFmpeg program to provide detailed progress information. With this patch, FFmpeg will output
the progress information in a JSON string that contains the data for each input and output stream individually. The JSON output is enabled
by default. It can be enabled with the global -jsonstats switch on the command line. Use the -stats switch
on the command line for the standard progress output.
Example output with -stats:
frame= 143 fps= 25 q=-1.0 Lsize= 941kB time=00:00:05.68 bitrate=1357.0kbits/s speed=0.995x
Example output with -jsonstats:
