-re – This option is used to slow the reading of on-disk files to real–time for live streaming output.You have a couple of problems with your options for ffmpeg. I also tried to create a #bin/bash script and calling this script from the pipe url in tvheadend, but no luck. Question is, why is it not working with my vaapi command. So pipe is fundamentally working in tvheadend. I was able to make a pipe working with avconv and an online rstp stream, but not with vaapi. 09:48:31.623 iptv: stdin pipe unexpectedly closed: No usr/bin/ffmpeg -re -y -vaapi_device /dev/dri/card0 -hwaccel vaapi -hwaccel_output_format vaapi -i /home/hts/in.mkv -an -vf 'format=vaapi|nv12,hwupload' -c:v h264_vaapi -qp 20 -f mpegts -tune zerolatency -f mpegts pipe:1 When I try to create a pipe in tvheadend (in the url text box) i put usr/bin/ffmpeg -re -y -vaapi_device /dev/dri/card0 -hwaccel vaapi -hwaccel_output_format vaapi -i /home/hts/in.mkv -an -vf 'format=vaapi|nv12,hwupload' -c:v h264_vaapi -qp 20 -f mpegts -tune zerolatency -f mpegts out.ts I have the ffmpeg command working with vaapi.

So from the previous example, the video filter becomes: -vf 'format=nv12|vaapi,hwupload,scale_vaapi=w:h' where w and h are the width and height of your new video.Īs a note, you might need to ensure that the user running the command is a member of the video group, or which group has write access to /dev/dri in order to use VAAPI. If you also need to resize the video, use the scale_vaapi video filter just add it as an additional filter to the -vf option.

That will take input from the standard input (such as for use with pipe://), use VAAPI to encode the video the H.264, but copy the audio stream as-is without re- or transcoding, and pass it back out to the standard input. Then, when you construct the command line for ffmpeg:įfmpeg -hwaccel vaapi -hwaccel_device /dev/dri/render/D128 -hwaccel_output_format vaapi -i -vf 'format=nv12|vaapi,hwupload' -c:v h264_vaapi -c:a copy pipe:1 To use VAAPI with ffmpeg, check if your build of ffmpeg has vaapi support built in with : ffmpeg -codecs | grep vaapi.
