I have a RPi2 available
for testing, I'll check with it if you can link to a sample file.

Hello everybody, Since I could't find anything about this problem I had to create a new post. 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=file://PATH_TO_FILE/video.mp4* 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... Got context from element 'playsink': gst.vaapi.Display=context, gst.vaapi.Display=(GstVaapiDisplay)NULL; Redistribute latency... Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstSystemClock Got EOS from element "playbin0". Execution ended after 0:00:00.000176603 Setting pipeline to PAUSED ... Setting pipeline to READY ... Setting pipeline to NULL ... Freeing pipeline ...* I even tried to use qtmux instead of mp4mux, but the results are the same. Does anyone had the same problem ?

Here is a sample video. Note that the beginning is slow because of the webcam. This is not a problem. I've tried to play it on my desktop using vaapi h264 decoder but had no success. Only VLC and Chrome browser can open it successfully. Em ter, 26 de jul de 2016 às 11:27, Digits <[hidden email]> escreveu:

It plays fine (after the
initial stall) from the command line with playbin on my Mac - I
will test it on my Raspberry tomorrow for you.

Nice !
Did you use any different parameter for the playbin command line ? Best regards, Christian |

Hi Christian,
I used your launch line. It does not play on my Pi either - the only strange thing I can see when playing on the Mac is the file being detected as Quicktime. Regards, Dave. On 27/07/2016 1:51 AM, argusroot wrote:
