Sluttering (how do I see the video with omx decode)
Is it a regression ? Was it working for you before on the same or other config ? I do not know. It is the first time that I use this configuration: omx for encoding and decoding. The only thing that I know for sure is that the effect gets worse and worse if I increase the frequency of key frames. Can you try gstreamer-vaapi ? to compare with another hw decoder. And with sw decoders in gstreamer it works ? And other players ? I am trying to determine if the issue is only in the omx decoder. I tried this combinations with gstreamer: sw encoding + sw decoding (libva): works sw encoding + omx decoding: works omx encoding + sw decoding (libva): works omx encoding + omx decoding : fails I havent tried vaapi yet. I can try to give it a try tomorrow and report results BTW: Are you aware of anyway that I can validate that a video is properly encoded, besides playing it? Thanks! We are trying with vappi and we cannot reproduce the bug. This is the pipeline that we are using: gst-launch-1.0 videotestsrc ! video/x-raw,width=800,height=600,framerate=60/1 ! timeoverlay ! videoconvert ! vaapih264enc ! video/x-h264,profile=main ! h264parse ! vaapih264dec ! vaapisink sync=0 --gst-debug=*:3 To sumarise ENC -> DEC : Result sw -> sw : OK sw -> omx : OK sw -> vappi : OK omx -> sw : OK omx -> omx : FAIL omx -> vappi : OK vappi -> sw : OK vappi -> omx : OK vaapi -> vappi : OK -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
