Re: RTSP > 1920 x 1080 --> HDMI?

^^
Ah, thank you for replying, and on Christmas, too!

I didn't realize there was a HW limitation for ffmpeg as well.

Is there a height limitation?

This makes me even grumpier that my brand-new RLC-410 doesn't support 2048x1536. Reolink removed that in favor of 2304x1296 "since that's also 3 MP."

RTSP > 1920 x 1080 --> HDMI?

I want to render the video from my BeeCam onto my HDTV via my Pi. The BeeCam outputs rtsp. The problem is that my BeeCam is a Reolink RLC-423S with a _minimum_ output resolution of 2304 x 1296, which is larger than the maximum size of 1920 x 1080 that omxplayer can handle. I do have ffmpeg running o...

Re: Any way to add alsa support to ffmpeg without recompiling?

2. If ffmpeg is not compiled with alsa support there is no way to stream audio, so it would be a silent video. If you don't want or need audio, there is a way to substitute a "dummy" audio device, since YouTube will reject live stream feeds without sound. I had this same problem. Another solution i...

 No, unfortunately not. You must recompile ffmpeg to add enable additional libraries. Below is the script I build to compile ffmpeg with alsa, fdk-aac, and libx264 support.
Thanks! I don't know why I didn't see this earlier. I'll try this when I get back from my trip.

The good news is that I have 2 watchdog timers going--one on the ffmpeg relay station (on another Pi, because I can't get ffmpeg compiled on this one, due to a /tmp that's too small, and my lack of knowledge on how to resize that), and...

Re: PHP/Bootstrap Web Interface for the Pi Camera

The author of that script suggests I specify a file in the ramdisk at /tmp , but the problem there is that /tmp is empty at startup, which causes the uv4l driver to fail the text overlay due to a missing file, even if that file gets created a few seconds later. Ideally I'd start my UpdateDateTime.s...
