  • Encoding for JMF

    8 mars 2012, par stimms

    I'm creating some videos from a collection of images, I subsequently wish to play this video back with java. I found JMF but I haven't been able to find an encoding which is actually playable by it. Does anybody have an ffmpeg or mencoder formulation which produces JMF playable output ? I would also take alternatives to JMF if there is something better.

  • A/libc : Fatal signal 7 (SIGBUS)

    29 août 2020, par yejafot
    A/libc: Fatal signal 7 (SIGBUS), code 1, fault addr 0xb92df158 in tid 19864 


    


    App crashes when app launches. How to find which line throws this error in .cpp file inside android studio using this fault addr 0xb92df158 ?

    


    And this error not occurs everytime i select the video(small or large size video) from app but only sometimes it occurs. Is there anyway to debug the line inside .cpp file because i have so many null checks and error handling inside .cpp file. What i do is i select video from java and edit the video inside .cpp file and save back the output image inside sdcard using

    


    char buf[1024];
snprintf(buf, sizeof(buf), "%s-%d", "/storage/emulated/0/Download/frame.png", av_codec_ctx->frame_number);
pFile = fopen(buf, "wb");
fprintf(pFile, "P5\n%d %d\n%d\n", av_frame->width, av_frame->height, 255);
for (y = 0; y < av_frame->height; y++)
    fwrite(buf + y * av_frame->linesize[0], 1 , av_frame->width, pFile);


    


    .So while decoding or saving back as .png i think i get this sort of error.

    


  • FFMpeg HLS to MXF video codec copy non monotonically increasing dts issue

    22 juin 2023, par arlovande

    I am rewrapping an HLS stream as an mxf file. The HLS is 1080p59.94 10bit 4:2:2. The mxf is a video codec copy and an audio conversion to pcm. The stream has video timecode burn-in for me to watch the video frames. Here is the command

    


    ffmpeg -i "https://myinput/index.m3u8" -f segment -timecode "01:01:01:00" -segment_time 600 -reset_timestamps 1 -c:v copy output_%03d.mxf


    


    I get the following non-fatal error

    


    "Application provided invalid, non monotonically increasing dts to muxer in stream 1"


    


    The file is still created, however. In VLC the file plays correctly frame by frame. But in Adobe premiere when I play frame by frame I get video stuttering and I see the timecode burn in plays in a sequence like this... 3 frames ahead, then 2 frames back... so the frame sequence would be something like ;03 ;01 ;02 ;06 ;04 ;05 ;09 ;07 ;08

    


    It's almost like Premiere does not know how to order the frames back together but VLC does. Any thoughts on how I might change the command to reorder the dts monotonically ?

    


    When I wrap to a .ts file I don't get this issue in Premiere, but I need MXF because Premiere can play an MXF file as a growing file.
