  • Multiple call to ffmpeg main fails in Android

    27 mars 2016, par fatih orhan

    I have ported ffmpeg library to Android. Using JNI interface, I am able to run ffmpeg commands by giving arguments to ffmpeg’s main method, just like from command line.

    In order to get a specific part of a video, I use this command :

    ffmpeg -i /mnt/sdcard/input_video.mp4 -ss 00:00:12 -t 00:00:10 -an /mnt/sdcard/output_video.mp4

    and it works great. The video is split from 12. seconds to 22. seconds and the video is saved, the method returns normally (as 0).

    However, if I make a second similar call (different start time for example) just after the first one is completed, ffmpeg is not able to process the request and it throws a segmentation fault.

    For the first call, it gives such an info :

    Guessed Channel Layout for Input Stream #0.0 : mono

    and works. But for the second, the message is like this one :

    Guessed Channel Layout for Input Stream #1.0 : mono

    and it doesn’t work. I don’t know if it has something to do with the error.

    The problem, in general, should be related to static global variables (I think) but I could not manage to reset them properly. What might be the solution to make multiple successful calls to the main method of ffmpeg ?

  • How to start Quicktime streaming immediately

    16 octobre 2012, par forthrin

    I am trying to make Quicktime files stream from a HTML document using the <video></video> tag.

    The video format is :

    Video: h264 (Main), yuv420p, 640x360, 2175 kb/s, 24 fps, 24 tbr, 24 tbn, 48 tbc
    
Audio: aac, 48000 Hz, stereo, s16, 104 kb/s

    However, the browser does not start playing the video until after downloading the whole file (which takes minutes). I, of course, want the video to start streaming as soon as possible.

    The guy who gave me the video files has recollection of some "Streaming friendly" output option in his video editing software that resolved a similar problem earlier. However, many of the video files don't have original project files anymore and thus cannot be regenerated.

    So my question is : How can I make the existing video files stream immediately ? (I have FFMPEG on my machine) ? Or does the solution lie elsewhere ?
