This is broken (because odd width is not supported by

The following does work and produces the same black edge:

Good day to all.
I'm using libav in my application to encode live video to h264, mux it
in Live Smooth Streaming format and send to IIS Live Smooth Streaming
publishing point (via http).
I need to achieve quite low latency (3 seconds) of live video. When
the video is recorded on regular frame

What is my observation is after i got following debug print

Definitely!

I am not using the latest build, but for me the
round-trip worked without artifacts
I forgot to add -pix_fmt yuv420p to

That means Delay will be there?? which is not at all acceptable. Any way
is there to avoid this?
One more thing is transmitter (Camera) sending only i-frames. not
B-frames. Then how this print is comming?

i think theoretically its possible but it might be bit complex..

Dear all,
I am developing an application which uses ffmpeg library as below:
* Add ffmpeg binary to application source code
* Call ffmpeg command line via C# code.
I want to sell my application. Do I have to pay for using ffmpeg? And if
I have to pay, who will I have to contact?
Sorry

do you tune rc_lookahead to zero?
Do you mean x264's rc_lookahead? Tried it, but latency was the same.
Anyway that seems not to be encoder problem (as frame encoding time
doesn't change a lot when changing frame rate).
