# Patches
FFmpeg patches.
## No PTS
Ignore packets during streamcopy that don't have a valid PTS value.
## HLS bitrate
Calculate bandwidth estimate for the hls master manifest.
## JSON stats
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
