Hey everyone,
I'm a little new to GNURadio, so sorry if this question sounds dumb. I'm
using GNURadio3.7.13.4. I read about how metadata worked from
https://www.gnuradio.org/doc/doxygen/page_metadata.html and wanted to try
it out. I have a file metadata sink directly downstream from a block
Typo. Should be:
ffmpeg -i test.mp4 -c:v libx264 -b:v 11M -minrate 11M -maxrate 11M
-bufsize 8M -c:a copy -muxrate 12901961 test.ts

First, you have to match the TS rate to the symbol rate. The equation is:
Symbol rate * 2 * 188/204 * code rate
For the example flow graph:
800 * 2 * 188/204 * 7/8 = 12.901961 Mbps
Second, you need to constrain the video bitrate to fit into the selected
TS bitrate. With ffmpeg, something
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
Hi All
did some transmission test in DVB-S tonight
TX : ffmpeg + gnuradio + pluto SDR
RX : RTLSDR + sdrangel
it works but there are some gaps in the received signal because the TS
stream bitrate is slightly less to the maximum usable bitrate
is it possible to add some bit stuffing at DVB-S
Great news! DPDK support is an interesting development. Is there any
documentation or examples which show this capability?

The release candidate of UHD version 3.14.0.0 has been tagged and is
available for testing. This API release introduces support for the N320
and N321 USRPs soon to be released (watch for the announcement on ettus.com!),
a DPDK-based transport, and several other features and bug fixes. This
