Video4Linux on RPi working now on UxPlay: could be backported to RPiPlay. #334

Open fduncanh opened 2 years ago

fduncanh commented 2 years ago

GStreamer OpenMAX plugin omxh264dec was broken for a long time, but now the development branch of GStreamer has got Video4Linux plugin v4l2h264dec working for hardware accelerated video on the R Pi GPU. This is the one to be supported in the future on Pi.

see https://github.com/FDH2/UxPlay/issues/70 The GStreamer-based RPiPlay offspring UxPlay on RPi OS bullseye (32 or 64 bit) and Manjaro-Arm-RPi4 works with the patched plugin. (backports to GStreamer 1.18.4 (bullseye) and 1.20.0 (Manjaro) are available)

EDIT: The patch for GStreamer-1.18.5 (used by Ubuntu 20.10) is also now available,

Here are some reports of success of UxPlay with Raspberry Pi model 4B using Video4Linux2 for GPU h264 decoding

Dear developer,good day! May I ask how to Make sure the DUMP flags are not active ? How to check it? Thank you

No idea what DUMP flags are. You can test UxPlay on RPi with Video4Linux2 at the UxPlay site https://github.com/FDH2/UxPlay . you will need to patch the gstreamer Video4Linux2 plugin as explained there, until GStreamer-1.22 is released. This is for RPi OS Bullseye, Ubuntu 22.04, etc. There is no support for older GStreamer < 1.18.4, as in a Debian Buster-based OS with 1.16.2

Dear developer, DUMP flags is from your README.md, quote"For best performance:

Use a wired network connection Compile with -O3 (cmake --DCMAKE_CXX_FLAGS="-O3" --DCMAKE_C_FLAGS="-O3" ..) Make sure the DUMP flags are not active Make sure you don't use the -d debug log flag Make sure no other demanding tasks are running (this is particularly important for audio on the Pi Zero)"

@kang000feng RpiPlay and UxPlay are now different projects. UxPlay supports RPi using gstreamer and video4linux2.(32 and 64 bit) RpiPlay supports RPi using Omx (32 bit) / If you need UxPlay support, and its documentation doesnt solve it, post your issue there.
