Hello. I am currently streaming MPEG4 from IP cameras (RTSP protocol) and need to be able to switch from a camera to another one very quickly (i.e. close one stream and open another one). I based my code on the excelent tutorial from http://www.dranger.com/ffmpeg/. However I have several problems / issues I would like to resolve. Note that I am using FFMPEG svn 15339.
- I must enable anonymous viewer login in the IP camera settings because authentication is supported. From what I've seen on another post (http://lists.mplayerhq.hu/pipermail/libav-user/2008-December/001762.html), this is still not supported. Is this right ? I looked a bit and it seems it would be easy to support rtsp://login:p...@ip/stream urls as the http protocol already support that. Again, am I right ? I could do this but I would like to have some input from you as I am not a FFMPEG expert. - The first frames of the stream that I display are not complete (display errors...) and this has a big negative visual impact. If I am not mistaken this is because FFMPEG did not receive already a keyframe. Is there a way to be sure to have received one to avoid the incomplete display ? - Calling av_find_stream_info takes a lot of time (up to 4-5s) and this is something that I would like to avoid as, as I said, I need to be able to switch quickly from a camera stream to another one ? I have found out that I could skip the call to av_find_stream_info when using MJPEG streams but not with MPEG4 streams. Anyone can tell me one I could reduce that delay (1 or 2s would be more acceptable) ? Thank you forward for your answers, Sebastien _________________________________________________________________ Send e-mail faster without improving your typing skills. http://windowslive.com/Explore/hotmail?ocid=TXT_TAGLM_WL_hotmail_acq_speed_122008 _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
