• using gstreamer splitfilesrc to play consecutive .mp4 (H.264) files

  13 juin 2014, par user3736170

  I’m trying to string together and play multiple mp4 files as one file. Each file is about 1 minute in duration, each starting with a pts of zero. Each file plays fine as a single source using gstreamer’s filesrc.

  I’m using the following command line with the splitfilesrc :

  gst-launch-1.0 splitfilesrc location="test*mp4" ! qtdemux ! h264parse ! avdec_h264 ! videoconvert ! ximagesink

  My source files are test1.mp4, test2.mp4, etc

  This plays the first file fine and then stops. I turned on debug messages, and I see that the qtdemux filter requests (one minute’s worth of) packets from the splitfilesrc, and then determines that it has reached the end (debug message states "no more moofs", after the qtdemux gets the last fragment from the first file). The pipeline then gets destroyed due to eos.

  Is this gstreamer splitfilesrc pipeline possible with mp4/H.264 files ? I’m pretty sure it works with mpeg2 ts files, where the files are produced from a single large file using gstreamer’s own multifilesink. How about these mp4 files, which were produced with ffmpeg ?

  Thanks for any insight.

• Play AAC in SoundManager2 won't start

  27 novembre 2012, par sasa

  I converted audio file MP4 to AAC and then want to play that file in SoundManager2. If I use some software for Windows for convert, everying is fine, audio is playing well. But, on server side when MP4 file is converted to AAC using ffmpeg, file is loaded in SM2, but playing is not started.

  I use this command :

  ffmpeg -i in.mp4 out.aac

  Here is SoundManager2 log :
