problem in transcoding (ffenc_h263)

[tom1]

Hi All,

I have created a pipeline that act as a gateway between two nodes for trans-coding data. My pipeline receives data from node 1 over RTP, trans-code it (using decodebin and ffenc_h263) and send it to node 2 over RTP. Actually my pipeline is changing the bit-rate of incoming RTP Stream by trans-coding it.

My Pipeline is working fine, but i am facing the problem with output video quality. On the start of the pipeline, video quality of output stream is acceptable enough but it degrades with time. After two to three hours video gets blurred. I have tweaked with various settings of H263 Encoder but did not able to fix the problem.

Is anyone there who can suggest the reason of this behaviour? Any help would be greatly appreciated.

Thanks

Hi Experts, I have further analyzed the problem and found bitrate gets drop after some time. Because of this output video quality degrades. Can some share why encoder bit rate is dropping after some period of time?

Thanks
