I have read in the L4T docs that ffmpeg is supposed to support hardware accelerated decoding of specific video codecs but I have been unable to achieve smooth playback of the UHD and 4K h264 and h265 videos I have tested. I have had success playing hw accelerated videos under L4T with jetson-ffmpeg…

Hi, Please refer to this post: [image] Accelerated HW Decode with ffmpeg not working，Decoder h264 does not support device type cuda Jetson AGX Xavier Hi, Please check the steps of downloading source code in And the steps to configure/make/run ffmpeg with hardware decod…

Thanks for that DaneLLL! I’ve not tried building ffmpeg with that patch applied yet but according to this page: https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fmultimedia.html%23wwpID0E0JB0HA I don’t need to and nvv4l2dec shoul…

I should also note that the ffmpeg page is linked to in the Jetson Nano FAQ, which also neglects to mention having to rebuild with this patch. [image] Jetson Nano FAQ Jetson Nano Q: What power supply should I use with Jetson Nano Developer Kit? Please refer t…

I’ve given this a quick test now, but only with one h264 file. It seems to work when run with sudo but the patch fails to apply to both the latest git ffmpeg and the latest ffmpeg stable release. Instead you have to checkout the ffmpeg git commit from the end of May, right before this patch was rel…

Hi, The steps should work fine without building the source manually: $ echo "deb https://repo.download.nvidia.com/jetson/ffmpeg main main" | sudo tee -a /etc/apt/sources.list $ echo "deb-src https://repo.download.nvidia.com/jetson/ffmpeg main main" | sudo tee -a /etc/apt/sources.list $ sudo apt …

Thanks DaneLLL! The instructions at: https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fmultimedia.html%23wwpID0E0JB0HA Need to be corrected. The page is titled ‘Accelerated decode with ffmpeg’ but if you follow the instructions o…

I’ve had a quick look at the latest git mpv source and there is no link between ffmpeg and mpv as far as the hardware decoding is concerned, which makes me wonder which would be easier to port to mpv , nvv4l2dec or nvmpi, the jetson-ffmpeg decoder/encoder? Here are all of the currently supported mp…

[image] allcoms: ffplay -vcodec hevc_nvmpi -i vid.mp4 ffplay -vcodec h264_nvmpi -i vid.mp4 Sorry for an offtopic. But how did you build the ffplay. When I install sudo apt install ffmpeg I see only ffmpeg and ffprobe in the /usr/bin Even when I build from sources I can only see those two …

Hi rreddy78 When you build jetson-ffmpeg or the regular ubuntu ffmpeg ffplay gets built, not the nvidia ffmpeg.

Hi @allcoms I didnt quite get what you say. I have a followed the instructions in this topic. And I get the results fine: rreddy78@jetson:~/ffmpeg-4.2.2$ ./ffmpeg -decoders | grep nvv4l2 V… h264_nvv4l2dec h264 (nvv4l2dec) (codec h264) V… hevc_nvv4l2dec hevc (nvv4l2dec) (codec hevc) …
