Hi,<br>
<br>
Well I am really stuck.<br>
<br>
My project is to dump Images from a live H264 stream using live555 and ffmpeg.<br>
<br>
I started with the testRTSPClient prog and in the afterGettingFrame method I want to send the fReceiveBuffer to a class that will decode each frames with ffmpeg and dump all images to a directory. But I can't find any clear sample code or clear HowTo method in order to do that.<br>
<br>
I have read some posts in the mailinglist. But it's not clear.<br>
How to create a suitable ffmpeg codec context for consuming the fReceiveBuffer ?<br>
What about using parseSPropParameterSets ?<br>
Do I have to use ffmpeg av_parser_parse2 method ?<br>
<br>
Any help would be appreciated.<br>
<br>
Thanks in advance,<br>
David.<br>
