The VideoLAN Forums

I have recently been working on a project to write a H.264 video encoder in C++, using the NVIDIA Video Codec SDK.

If I write the data to a file and try to play the file in VLC, the video successfully plays. But if I open a TCP or UDP server in C# and send the data to VLC over the network instead, VLC does not play the video. For what it's worth, I'm testing this on a Windows 10 machine.

The URL I'm trying to open is "tcp://127.0.0.1:22398".

This is the log for a successful session by opening the file: https://pastebin.com/bccg3unc

And here is the log output for an unsuccessful play over a TCP stream: https://pastebin.com/24WnC4KK

This is with the H.264 demuxer selected in the VLC GUI options. If I leave the demuxer set to "automatic", the file still doesn't play and it appears to try another one for MPEG-TS.

I am using VLC Player 3.0.6. Any ideas?

I changed the MRL to "tcp/h264://127.0.0.1:22398", but that didn't help. The logs at least now indicate that it tries to use the h264 packetizer, but it still fails to play.

"this doesn't look like a h264 ES stream" kinda tells it...

My mistake, it works now! I copied the output buffer from the C++ encoder the wrong way. My debugger showed zeroed bytes as empty spaces so it took me a while to notice the issue...
