MJPEG Transcoding
Posted: 10 Aug 2010 12:53
Hi,
I have an application which works only with MJPEG streams. I plan to used this software to process an MPEG4 stream.
So I thought of transcoding this real-time MPEG4 stream to real-time MJPEG stream.
I used this command line :
The transcoding is working but the quality is horrible, with pixels as large as my thumb !
However, when I try to transcode a MPEG4 file with this command line, the quality is quite the same as the original video.
What am I missing ? Is the quality limited since I read a real-time stream ?
I tried to improve the --rtsp-caching to 10000 ms but the result is the same.
Have someone an idea ?
Thanks.
