When appending videos, you usually need to match the specs for the video,
including dimensions, framerate, pixel format
filtered.mp4 is 640x352, 30fps
intro.mp4 is 1080x608, 59.94fps
My guess is that is part of the reason. The specs can change midstream for
a transport stream, but some player

Hello all,
My setup is as follows:
- Nginx with the RTMP module
- Multiple RTMP stream pairs, each one with a primary and backup RTMP endpoint
(so streaming to rtmp://localhost/main/$STREAM_NAME and

Agreed. While many won't read it before posting it is at least something
that could be pointed to in replies, FAQs, docs etc.

To understand how it works, you need to think of frames not as punctual
instant in time, it is an interval going from the frame's PTS to the

I'm using hardware encoding via FFMPEG, OpenCV and OpenMAX.
If I'm using FFmpeg h264_omx as a backend for VideoWriter() than I get
image like https://i.stack.imgur.com/H7Kg8.jpg. Colors obviously kind of
mixed.
Other backend codecs work fine. My test code: https://pastebin.com/z1igaSsA

I now appreciate that 'blend' has a "preferred" input similar to 'overlay',
but that behavior is not
documented. In the case of 'overlay', the name "main" doesn't convey that
