ffmpeg - How to detect video bitrate from HLS/M3U8 file using ffprobe -

we need detect video bitrate of hls stream ffprobe using m3u8 file of .ts.

if use m3u8, can duration, dimensions, codecs used, audio bitrate, no video bitrate available in response provided ffprobe.

in sample above, know video around 520kbps, need find way read programatically either ffprobe or other way. have can of information needed, i'm missing 1 important value video bitrate.

what other options try?

thanks!

for video bitrate can do:

ffprobe -select_streams v:0 -show_entries frame=pkt_size,pkt_duration_time <input> 

to compressed packet sizes , durations (in bytes , respectively seconds) series of frames. run while calculate average bitrate total duration.
