I've spent 2 days studying frame.h, pixfmt.h, dpx.c, packet.h, and escape124.c.
I haven't learned a damn thing.
Despite their vagueness and ambiguity, reading and understanding H.222 & H.262 are dead easy by
comparison [1].
I just want to understand the frame structures that ffmpeg creates,

In frame.h, I think that this line:

should be:

How do I confirm it and make the correction?
Thanks!

Hi !
I'm trying to record a MP4 rtsp transport stream directly to a seekable file
and stream it to youtube at the same time.
I've got the stream and recording working, but the recorded file is not
seekable.
I'm using this in a shell script:
/usr/local/ffmpeg/ffmpeg \
-rtsp_transport tcp -i

Hi Usman,
I don't think that this is a client problem. I think that the server might
be lagging behind real-time stream.
The output you have there appears to say it's 4.6 fps and i imagine that
the native file is meant to be higher frame rate than that?
The output which will help diagnose this
Hi Chris,
I have observed that the machine that is receiving stream is lack behind as
the streaming server approaches the fps count of around 200 or above when
the client starts streaming the fps. Kindly guide me. should I replace the
client machine?
Thanks.

Hi Usman,
You may wish to look into whether the machine which is encoding is able to
keep up realtime when you see something like this. More than likely, it is
running out of resources (either from encoding or from the source material
in the form of a bad network mount). Without more information
at streaming server:
ffmpeg -i v1.mp4 -an -c:v libvpx-vp9 -pix_fmt yuv420p -preset slow
