Hello, I am having some issues receiving RTSP image data from an IP camera. We get into a state where we can receive the data, feed it into the codec via avcodec_decode_video2(...), but we never get signaled that a full frame is ready for use (via the got_picture_ptr parameter). The return value for the function is > 0, so there is some bytes being decoded. If I restart the application, or start another instance of the same application (on a different PC, because of the application itself doesn't allow me to start 2 instances) , then we can get the video frames correctly, so that rules out networking and camera issues.
We currently call avcodec_flush_buffers(videoDecContext) to try and reset the the codec, and I can't find any non-pedagogic examples floating around on the internet. Here's a sample of a dump of stderr when the logging level is set to WARN. [h264 @ 034ee100] illegal short term buffer state detected > [h264 @ 034ee100] mmco: unref short failure > [h264 @ 94c89660] no frame! > [h264 @ 94c89660] no frame! > [h264 @ 9254e960] no frame! > [h264 @ 94c89660] no frame! > [h264 @ 94c89660] no frame! > [h264 @ 94c89660] no frame! > [h264 @ 94c89660] no frame! > [h264 @ 94c89660] no frame! > [h264 @ 9254e960] no frame! > Any thoughts? -Randy -- Randy Ly System Analyst Searidge Technologies <http://www.searidgetech.com/> 19 Camelot dr, Ottawa, ON <https://twitter.com/Searidgetech> <http://www.linkedin.com/company/searidge-technologies>
