h.264-encoded video from fp 11 looks mangled when recorded
I'm streaming h.264 from a live conversation between two people, and storing via FMS. I've noticed that quite often, the recorded video seems to have out-of-order frames or other issues that result in poor quality video, although the live stream when viewed live at the other client looks fine. Here's an example:
I always see similar blocking when I initially begin streaming the other client's h.264 content, but this generally resolves within ~1 or 2 seconds.
Using the following h.264 settings:
var h264Settings:H264VideoStreamSettings = new H264VideoStreamSettings();
h264Settings.setProfileLevel(H264Profile.BASELINE, H264Level.LEVEL_2);
_netStream.videoStreamSettings = h264Settings;
A few more notes on this that might be helpful:
- I've tried both RTMP and RTMFP connections - both result in the same issue
- I don't always see the issue with recorded video, but it's quite common (~50% of the time)
- The live stream does not look messed up at all to the other client (except for the initial stream connect for the first few seconds)
- The recorded stream, when transcoding via ffmpeg, produces a lot of errors:
- [h264 @ 0x101014c00]non-existing SPS 32 referenced in buffering period
Last message repeated 3 times
[h264 @ 0x101014c00]number of reference frames exceeds max (probably
corrupt input), discarding one
[h264 @ 0x101014c00]non-existing SPS 32 referenced in buffering period
- [h264 @ 0x101014c00]non-existing SPS 32 referenced in buffering period
Any help would be much appreciated!
