    I want output instead like this :

    


    chunk-stream0-960x540-00001.m4s
chunk-stream0-960x540-00002.m4s
...
chunk-stream0-960x540-00044.m4s
chunk-stream0-960x540-00045.m4s
chunk-stream1-320x170-00001.m4s
chunk-stream1-320x170-00002.m4s
...
chunk-stream1-320x170-00044.m4s
chunk-stream1-320x170-00045.m4s
chunk-stream2-???????-00001.m4s
chunk-stream2-???????-00002.m4s
...
chunk-stream2-???????-00074.m4s
chunk-stream2-???????-00075.m4s
init-stream0-960x540.m4s
init-stream1-320x170.m4s
init-stream2-???????.m4s
master.mpd


    


    where ??????? could be just audio or 48000hz or whatever.

    


    The Question

    


    Is there a way to include the stream's width and height (its size) in the outputted filenames from the command-line interface ? If no, how could it be accomplished using a shell script for example.

    


  • ffmpeg : scale output cropped width/height doesn't work

    10 septembre 2012, par Meir Gerenstadt

    I'm trying to crop video frames with ffmpeg, and I would like to scale the cropped image automatically.
    I saw an option at av filter : http://ffmpeg.org/libavfilter.html#SEC41

    ./ffmpeg -i video.mp4 -vf "crop=640:480,scale=ow:oh" -f mpegts udp ://127.0.0.1:1234

    I receive an error : Error when evaluating the expression 'oh'

  • Stripping 'actual time of day' from AVI files

    22 avril 2014, par wxJunkie

    I have TB’s of AVI|DV|VOB files. I want to run a script that will enable me to find the real start time + end time AND the navigation (latitude & longitude) that is embedded in the audio of each of the clips that I have and export the list perhaps to a .txt or .doc list. I use a SMPTE reader now that can read the time that is embedded in the video, so there has to be a script that will pull those certain criteria’s out ?

    I have ran several codes in the past that has given me :
    duration : 00:01:23.83 start : 0.0000000, bitrate 28771 kb/s etc.
    I always get ’start : 0.0000000’ for each clip and I need the real start time of each clip.

    Is this possible ?
