  • 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.

  • Convert GIF to MOV with alpha FFmpeg

    20 juillet 2022, par Евгений Греков

    I'd like to convert GIF animation file with transparency to MOV with alpha channel.

    


    So I tried

    


    ffmpeg -i input.gif -c:v hevc_videotoolbox -allow_sw 1 -alpha_quality 0.75 -vtag hvc1 output.mov

    


    As a result I get MOV file that plays perfectly (with transparency) in QuickTime, but it's not transparent in browser (Safari, Chrome, mobile and desktop).

    


    How do I fix it ?

    


    Thanks.

  • Can you sync multicast video feed with live feed ?

    15 juillet 2022, par Taavi Sõerd

    I am using android studio to stream live video via UDP multicast. my problem is that video feed on the android app plays in "slow motion" so every second real time is played as two seconds in the video feed. My question is that can I sync the video feed in the app to latest UDP packet ? I'm using Java so and I'm very new to UDP and especially multicast, thanks !
