  • ffplay displays runtime error, yet still plays file

    11 mars 2016, par John Doe

    Im Working with pydub, and I’m using ffplay. For some reason, when the program runs i get this ’error’ :

     /usr/local/lib/python2.7/site-packages/pydub/utils.py:178: 
    

    
RuntimeWarning: Couldn't find ffplay or avplay - defaulting to ffplay, but may not work
    
  warn("Couldn't find ffplay or avplay - defaulting to ffplay, but may not work", RuntimeWarning)

    However, it still plays the selected audio file.

    1. Is there a way to make this warning disappear, as it happens every time i play it ?
    2. If i can’t, is there anyway i can configure this so that it uses pyaudio to play the stream ?

  • ffmpeg-mp4box-mpeg dash plays only few segments

    30 octobre 2015, par Idris

    Need help in debugging the segment dash files

    The input was an MP4 with these details. This was recorded from a video camera, the output from the camera was mkv and we converted into MP4 after editing the audio via adobe

    • Size : 7.51 GB Frame rate : 25 frames/ second
    • Data rate : 25326kbps
    • Total bitrate : 25525kbps

    Converted this to another mp4 with this command

    ffmpeg -i "input.mp4" -s 1280x720 -c:v libx264 -b:v 750k -bf 2 -g 75 -sc_threshold 0 -an video_1280x720_750k.mp4
    

    
ffmpeg -i "input.mp4"  -c:a aac -strict experimental -b:a 96k -ar 32000 -vn audio_96k.mp4

    The output video has

    • fps : 25
    • Data rate : 761kbps
    • bitrate : 761kbps

    Then, created the segmented dash through MP4Box

    MP4Box -dash 10000 -frag 10000 -rap -segment-name video_0_1280000\segment_ video_1280x720_750k.mp4
    

    
MP4Box -dash 3000 -frag 10000 -rap -segment-name audio_0_96000\segment_ audio_96k.mp4

    The MPD generated was validated online and its perfect

    UPDATE ! Included the MPD file

    Played the video through dashjs.. I believe it just plays the initial segment and errors out as MEDIA_ERR_DECODE..MEDIA_ERR_SRC_NOT_SUPPORTED.. or some message which says start not found..

    Through chrome debugging I see that atleast 4 segments are correctly loading.. I am not sure whats going on..

    Any help in debugging the issue is really appreciated. I really can’t understand if this is a problem with the file or ffmpeg or mp4box or chrome.

    Output from chrome debugging tool
