[QUESTION] how to use vp8enc?

[mattfeury]

Hello,

I am attempting to use the gstreamer sample. It is working well with the default x264enc. However, I'm interested in trying vp8enc. I'm using the pipeline listed in the comments, but when running I get:

2023-04-11 15:44:22 DEBUG   getNextNaluLength(): Warning: Failed to get the next NALu in H264 payload with 0x5c000003
2023-04-11 15:44:22 ERROR   writeFrame(): operation returned status code: 0x5c000003

over and over again. seems like writeFrame is expecting a h264 frame, which i'm obviously not using anymore. are there other changes required to get vp8 encoding working?

You also need to set up the appropriate transceivers:

i haven't changed the sample code besides the gstreamer pipeline. is it basically just changing videoTrack.codec? searched the project but didn't see any documentation on it
