  • ffmpeg can not dump RTSP streaming but ffmplay can play

    12 mars 2014, par poc

    I want to dump the RTSP streaming into a file.

    ffmpeg -y-i rtsp://172.19.12.37/live.sdp -acodec copy -vcodec copy tmp.mp4

    But I got errors,

    [mp4 @ 0x7fe98400dc00] track 1: could not find tag, codec not currently supported in container

    Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted

    However, I can play the RTSP streaming by any media player, what was wrong with my ffmpeg command ?

    Is there any options can dump any stream and dump it into identical video format.

  • ffmpeg missing blend filter

    13 mars 2014, par user2927954

    I am working on android project using ffmpeg library. I followed instruction from : https://github.com/guardianproject/android-ffmpeg to build ffmpeg library for android. All are OK.

    Now, i am testing filters that corresponding to video filter of this library such as : drawtext, scale, pad, ... Most of them worked fine, but i have problem with "blend" filter.

    I try with commands : ffmpeg -i input1.mp4 -i input2.mp4 -filter_complex blend=all_expr='if(eq(mod(X,2),mod(Y,2)),A,B)' -y out.mp4 and recieve error : no such blend filter.

    Do you know how i configure to enable this filter ?

    Here is the output result :

  • ffmpeg not converting via PHP script

    16 mars 2014, par user3331834

    Essentially, I have this code :

    if(in_array($ext,$audio)&&($ext!=="flac")){
    
    exec("ffmpeg -i -loglevel 'verbose' ".$fileName.".".$ext." ".$fileName.".flac null >/dev/null 2>/var/www/resources/ffmpegAudio.log &",$ffmpegOutput);
    
    print_r($ffmpegOutput);
    
    $editApproveStatus="Audio entry approved. File converted.";
    
}

    Ultimately, my goal is to convert files and show a live progress of the conversion (or at least something that updates every few seconds), and running in the background, so that the same page can be used to convert further files.

    Now I'm already stuck, because the conversion just isn't working. I know that the preceding code should be fine, since it makes it all the way to this if statement above, and no errors are being throw up by the PHP. However, my log output shows :

    ffmpeg version 0.8.10-6:0.8.10-0ubuntu0.13.10.1, Copyright (c) 2000-2013 the Libav developers
    
  built on Feb  6 2014 20:59:46 with gcc 4.8.1
    
*** THIS PROGRAM IS DEPRECATED ***
    
This program is only provided for compatibility and will be removed in a future release. Please use avconv instead.
    
-loglevel: No such file or directory

    Which also leads me to another question : If ffmpeg is deprecated, and avconv is the way to do, can I still use the exec code in my PHP as is (replacing the ffmpeg bit with avconv) ? From what I've seen so far on the avconv page, it looks similar, but I can't be certain that it's exactly the same.

    So my two questions : Why isn't the file being converted, and is there any change in the syntax between avconv and ffmpeg ?
