Hi,
I had the same issue, ffmpeg will not
provide CBR for MP4 , you might end-up with variable bit rates on
the TS stream. I had some good success with a target bit rate on
ffmpeg around 150% of the bit rate set on GNURadio. But this will
only work with real time inputs like webcam, when trying to run
with pre-recorded videos or files I had a huge headache to get a
"real" speed on the Rx side.
My set-up was similar to yours
ffmpeg+gnuradio+hackrf one and rtlsdr+sdrangel on rx
Using a webcam as input it worked fine
for me with around 125 to 150% bit rate on ffmpeg over the one at
the gnuradio/sdrangel value.
Let me know if you want to know more
about my settings.
Regards,
Raydel, CM2ESP
