So I'm using a RaspberryPi to generate h264 videos from a sequence of jpegs that I get from a webcam. *this is my current pipe:* gst-launch-1.0 -e v4l2src do-timestamp=true device=/dev/video0 ! videorate ! image/jpeg,width=640,height=480,framerate=15/1 ! jpegparse ! jpegdec ! omxh264enc ! video/x-h264,framerate=15/1, speed-preset=medium ! h264parse ! mp4mux ! filesink location= video.mp4 It is working like a charm, except that the videos can only be played with chrome or VLC. What I'm trying is to decode it again using gstreamer afterwards using the following pipe: *gst-launch-1.0 playbin uri=<a class="moz-txt-link-freetext" href="file://PATH_TO_FILE/video.mp4*">file://PATH_TO_FILE/video.mp4*</a> And it ends the execution before showing the first frame. *Setting pipeline to PAUSED ... Pipeline is PREROLLING ... libva info: VA-API version 0.39.2 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib/dri/i965_drv_video.so libva info: Found init function __vaDriverInit_0_39 libva info: va_openDriver() returns 0 Got context from element 'vaapidecode': gst.vaapi.Display=context, gst.vaapi.Display=(GstVaapiDisplay)NULL; Redistribute latency...
