<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I am experiencing an issue with openRTSP for which I've not yet been able to find an explanation. If there is a more appropriate forum for this or a FAQ I have missed, please let me know. I'm attempting to use openRTSP to capture and record the RTSP stream from an Extron SME-100 live streaming hardware encoder. The encoder is configured with a frame rate / GOP length of 30 fps, yet if I set openRTSP with a frame rate of 30 like this:<br>
<br>
openRTSP -d 300 -4 -w 640 -h 360 -f 30 -Q rtsp://URL > test.mp4 (or)<br>
openRTSP -d 300 -q -w 640 -h 360 -f 30 -Q rtsp://URL > test.mov<br>
<br>
The video is the incorrect speed and does not match the audio. If however, I set openRTSP with a frame rate of 60 with:<br>
<br>
openRTSP -d 300 -4 -w 640 -h 360 -f 60 -Q rtsp://URL > test.mp4 (or)<br>
openRTSP -d 300 -q -w 640 -h 360 -f 60 -Q rtsp://URL > test.mov<br>
<br>
The video is captured correctly and is synchronous with the audio for the duration of the capture. This is a perfectly viable work-around, but I'm curious about why openRTSP only seems to work as expected when set to capture at a 2x (actual) frame rate. Am I misunderstanding something about the use of openRTSP or the process by any chance? Anny insight that can be offered into this situation would be greatly appreciated; thank you!<br>
