graphics memory thought maybe that might be the difference between the logs
(hw decoder into gpu you probably need to specify format, especially when
its input is http, I don’t know if in ffmpeg the protocol takes mime type
into account.) For the compilation issues, check that you have cuda nvenc
ffnv… etc where they can be found by configure script, clean before make.

You are right, and all the inputs that are giving me troubles are indeed SD
MPEG2 video mpegts format. I tried searching on how to specify input for
hwaccel but can't find anything for mpegts....
