Hello guys, I had posted this earlier on the ffmpeg-user mailing list (and received no response) and it'd seem that this is the right place for this, due to the subject matter.
From the documentation available on FFmpeg's support for OpenMAX IL, the only backend I can confirm to be officially supported (correct me if I'm wrong) is the library provided for the Raspberry Pi, namely libbcm_host.so and libopenmaxil.so, satisfied by the packages libraspberrypi0 libraspberrypi-dev libraspberrypi-doc libraspberrypi-bin on raspbian. See line 140-145 in libavcodec/omx.c , doxygen entry https://www.ffmpeg.org/doxygen/3.1/omx_8c_source.html. The named packages above are related to Broadcom's VideoCore SIPs on the Raspberry hardware. When it comes to encoders, there is h264_omx. My questions are: 1. What platforms are supported by the current OMX implementation in FFmpeg, Bellagio? Is Xilinx-based hardware supported? 2. Can another OpenMAX IL backend, such as the library offered by Xilinx, see https://github.com/Xilinx/vcu-omx-il be added to FFmpeg in the same way as Bellagio's? That way, hardware such as Xilinx's Zync MPSoCs can be supported by encoders such as h264_omx above as an alternative to this solution shown here: http://fftrac-bg.ffmpeg.org/ticket/7214 The h264_onx encoder also offers an option for selecting a library name and prefix via the -omx_libname and -omx_libprefix arguments respectively, though I'm yet to test this option. Warm regards, Dennis. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
