Hi, running Ubuntu 20.04.3 32-bit on Raspberry Pi 3B+. Client is Kodi with TVH HTSP plugin running on networked PC.
The "pass" profile works. My h264_omx "webtv" profile I've created does not. The Broadcom OMX encoder seems to work OK according to TVH log, but I only get audio, no video in Kodi. Running ffprobe to inspect the output from the Rpi also shows an output with an audio stream, but no video stream.
The tvh log doesn't seem to show any problems, I see "libav: AVCodecContext: Using OMX.broadcom.video_encode". (Took a while to get to that point, was missing libs before but they're in place now).
My gpu_mem is set to 256 in /boot/firmware/config.txt and I have put libbcm_host.so and libopenmaxil.so from https://github.com/raspberrypi/firmware/tree/master/opt/vc/lib to my /opt/vc/lib directory. Ran sudo ldconfig after this, and TVH does find those libs now. I also ran chmod 777 on those libs, as well as sudo usermod -aG video hts
My build script was a small modification of one by Russell Tobin. The version I'm using is here: https://pastebin.com/qVyAqS5T

Any ideas or similar experience of getting "libav: AVCodecContext: Using OMX.broadcom.video_encode " from log, but no video in the output stream?
Also, tvh builds it's own ffmpeg during the make, but from my understanding, that ffmpeg can't be run as a standalone binary outside of TVH for debug, it's just the libraries (libav...) that get built, and not a binary. Is that right?
One final question: OMX is deprecated now on Raspberry Pi, with h264_v4l2m2m being preferred (and h264_v4l2m2m does work easily on Rpi3 for standalone ffmpeg builds). Will there be support for this h264_v4l2m2m added in TVH, alongside or instead of h264_omx? I can have a look at the TVH source and see if might be easy to add.
