However, when testing decodes for D1 resolution, the FPS I'm getting is great however the output from fakesink seems to keep hanging with greater than 5 decodes and not complete the video. The pipeline below is an example of how I am decoding 6 streams: gst-launch-1.0 -v filesrc location=/media/sdb1/H264_1080p30_test_video.avi typefind=true ! avidemux ! tee name=t ! queue ! vaapidecode ! fakesink silent=false \ t. ! queue ! vaapidecode ! fakesink silent=true \ t. ! queue ! vaapidecode ! fakesink silent=true \ t. ! queue ! vaapidecode ! fakesink silent=true \ t. ! queue ! vaapidecode ! fakesink silent=true \ t. ! queue ! vaapidecode ! fakesink silent=true For the D1 clips, I'm just replacing the video file with a cropped version. When adding --gst-debug=5, I am seeing that every so often some of the queues are empty. Could it be that the rate of the decoder is becoming greater than that of the copy to each queue and hence this could be the cause of the hanging? If anybody could clarify/verify this or offer another explanation it would be great and if there are any ideas on how to stop the hanging then it would be very much appreciated!
