  • ffmpeg running on windows with java

    24 décembre 2013, par Karn_way

    I have simple test class as

    public static void main(String[] args) throws IOException {
    

    
         String[] line = {"ffmpeg -i D:\\hadoop-video\\testVideo\\xyz.mp4 %d.png"};
    
         Runtime.getRuntime().exec(line);
    

    
    }

    when I try to run this I am getting

    Exception in thread "main" java.io.IOException: Cannot run program "ffmpeg -i D:/hadoop-video/testVideo/xyz.mp4 %d.png": CreateProcess error=2, The system cannot find the file specified
    
    at java.lang.ProcessBuilder.start(Unknown Source)
    
    at java.lang.Runtime.exec(Unknown Source)
    
    at java.lang.Runtime.exec(Unknown Source)
    
    at ImageTest.main(ImageTest.java:13)
    
Caused by: java.io.IOException: CreateProcess error=2, The system cannot find the file specified

    however file is present on my windows7 machine with location

    D:\hadoop-video\testVideo\xyz.mp4

    i tried removing .mp4 and then run also not working . please suggest what might be wrong

  • Why do I get different codecs on Windows and Linux with same code ?

    27 janvier 2016, par user3277340

    I am using the API version of FFMPEG to generate a MP4 file from a series of images. I specify the output by calling

    AVFormatContext *oc = NULL ;
    avformat_alloc_output_context2 (&oc,NULL,"mp4",NULL) ;

    Running the exact same code on Windows and Linux I get different codecs assigned. On Windows, the value of oc->oformat->video_code is AV_CODEC_ID_H264 (28), but on Linux I get AV_CODEC_ID_MPEG4.

    I tracked this down because on Windows my calls to avcodec_encode_video2(.,.,.,&got_packet) were always returning got_packet=0 so I never called av_interleaved_write_frame. I added a NULL AVFrame at the end to flush the video. But it was very small and did not contain the images I expected to see there.

    But on Linux everything worked just fine. So I went ahead and manually changed the value of oc->oformat->video_code and I got the expected results.

    My questions :

    1) Why do I get different codec types on different platforms with the same code ? Is there a parameter I need to set to force MPEG4 ?

    2) Is it "legal" to change this parameter after the call to avformat_alloc_output_context2 ? My concern is that "oc" has been properly initialized and, with the change, something may be inconsistent.

    3) Is there a way to force the MPEG4 codec on any machine ?

    Thanks.
