  • ffmpeg trim video works on emulator but fails on arm (real device)

    21 octobre 2017, par fthopkins

    I’m trimming the videos with ffmpeg that is bigger than 10 seconds. On my JNI edit function i use commands to trim video. I try to debug but as you all know debugging on JNI function is not like native android JAVA function. Maybe it is.. but not for my knowledge. Also i used coffecatch library to catch exception but didn’t succeeded. I did go for error step by step and reached the this line of ffmpeg main function.

    EDIT

    current_time = ti = getutime(); // edited : lastly can print message on here.
    
if (transcode() < 0) // transcode() < 0 => true and run exit_program(1).
    
    exit_program(1);
    
ti = getutime() - ti;

    On emulator everything is working good and fast. But on real device it gives some kind of error but i couldn’t catch it. When i check the Android Monitor of Android Studio my JNI edit function’s logs appear but disappear in a second. It is weird. Also when i check the output path on device, ffmpeg gives an trimmed video output (but very slow). So it is working on background and gives a trimmed video. It is very weird too because app crashes while main method is working. I need help to figure it out. I stucked.

    I debugged and found which line exiting me from the app. It is transcode() < 0 line But couldn’t find why ? Is there anyone to help me. I really need help. Can discuss and share more code.

  • Can open RTSP camera stream in FFMPEG but not in Gstreamer rtspsrc : Bad Request (400)

    6 août 2022, par Joran Apixa

    I have a Panasonic WV-SW559 camera set up as an RTSP stream.

    


    VLC can perfectly open the RTSP stream and display it, as well as FFMPEG.
However, when I try to set up a simple gstreamer pipeline, it does not want to open.
I execute the following command :

    


    gst-launch-1.0 rtspsrc --gst-debug=rtspsrc:5 location="rtspt://admin:12345@192.168.2.148:554/MediaInput/h264/stream_1" ! fakesink


    


    after which I get the following output :
