Re: Setting up network bridge under Buster

Little should have changed between Stretch and Buster regarding networking. The second part (bridged config) of the official access point documentation shows how to setup a bridge. The configuration in question defines an IP address for the bridge obtained via DHCP by dhcpcd. This should fit your n...

It's not what happens for me. You probably have set something somewhere. Check your profile settings.
I just had a look through my profile settings - couldn't find something relevant there. Are you using Safari as well?

Re: rPlay - Can't config my rPlay server

The version of rPlay that is available is obsolete - it seems it can no longer be activated and doesn't work with recent iOS versions. The rPlay developer has been regularly announcing an upcoming (paid) update for more than a year now (IIRC), but nothing was released to date. That's why I have star...

I hope this is the right sub-forum to post about the forum itself: For a few months now, the forum's post editor is center-aligning text for me. This makes writing a post a bit inconvenient.

Setting up network bridge under Buster

I'm trying to set up a bridge between two wired network interfaces, eth0, which is connected to a local network, and usb0, which is a device I'd like to provide with an Internet connection via the bridge. In addition to creating the bridge, I want the Raspberry Pi to remain accessible from the netwo...

It runs on the Pi 4 with both audio and video, but will disconnect and freeze the screen about every 30 seconds. Any ideas? 1. Pressing Ctrl+C on the keyboard should quit the program....

Re: Questions regarding H264 NAL boundaries

Just a small update: I found myself using an open source library for injecting max_dec_frame_buffering into the SPS NAL, and it's much more convenient to use with the byte stream format, so I won't further experiment on that domain. I guess there isn't too much of performance that can be won here an...

Re: Questions regarding H264 NAL boundaries

The most common use case is OMX_NaluFormatStartCodes where you have start codes and emulation prevention, and adding OMX_BUFFER_FLAG_ENDOFFRAME is used as the kick to tell the bitstream parser that it should have a whole frame to process (athough it'll still be happy should there not be a complete ...

Questions regarding H264 NAL boundaries

I'm using OpenMAX for decoding an H264 stream (coming from an iOS AirPlay Mirroring connection) under Raspbian on a Raspberry Pi. I'm receiving data in packets, with (AFAICT) one NAL unit per packet. I'm then forwarding the individual NAL units to the OpenMAX H264 decoder. In my current working solu...
