RTSP streaming issues

SKA

Hi! I need to be able to network stream to VLC with caching set to 0ms. It seems like older SDKs stream just fine with 0ms cache, but SDK 1.6.0 does not.

Using SDK 1.4.0, I'm able to stream with no problems. The voxl-streamer version is 0.7.5, and I also switched over to voxl-streamer 0.8.0 (from SDK1.6) to narrow down the root cause of the problem, but noticed that streaming worked in this configuration too.

Then, I flashed the voxl to SDK 1.6.0, and tried both versions of voxl-streamer (0.7.5 and 0.8.0) and neither of them were able to stream with 0ms cache.

Where should I look to solve this problem? Thanks!

For reference, here's my voxl-streamer.conf:

voxl2-mini-test-fixture (TF-M0104):/$ cat etc/modalai/voxl-streamer.conf
{
        "input-pipe":   "hires_misp_color",
        "bitrate":      3000000,
        "rotation":     0,
        "decimator":    1,
        "encoder":      "h264",
        "port":         8900
}

Following up on this, @Alex-Kushleyev do you have any initial leads that might help me - thanks!

Hi @SKA ,

Can you please clarify a few things:

using latest SDK, does rtsp streaming work, if you do NOT specify 0ms cache?
what player are you using for receiving the video? have you tried ffmpeg (if so, what is the full command?)
are you sure that you are actually have the hires_misp_color stream available from the camera server? you can check it using either voxl-portal or using voxl-inspect-cam hires_misp_color.
