Hi,
I tried the example on http://www.gstreamer.net/wiki/MultiFileSrc However, the output file seems to contain only one frame. Here is what I do in detail: > gst-launch --version gst-launch-0.10 version 0.10.28 GStreamer 0.10.28 https://launchpad.net/distros/ubuntu/+source/gstreamer0.10 > gst-launch videotestsrc num-buffers=1000 ! pngenc snapshot=false ! multifilesink location=test%05d.pngSetting pipeline to PAUSED ...

Setting pipeline to PAUSED ... Setting pipeline to READY ... Setting pipeline to NULL ...

Hi,
another person was able to confirm this on another machine. Does somebody know why this isn't working?

Hi,
I use snapshot=false for pngenc during the creation of the files. All 1000 files are created. pngdec which I use in the video creation pipeline does not have a property snapshot. Aslo, judging from the execution time, I have the impression that all images run through the pipeline somehow.

You need to provide a framerate to pngdec, otherwise it will assume it is a single image decoding and push EOS right after the first frame.

Hi,
my initial launch line contained: caps="image/png,framerate=30/1,pixel-aspect-ratio=1/1" But even if I try > gst-launch multifilesrc location=test%05d.png caps="image/png,framerate=25/1" ! pngdec ! ffmpegcolorspace ! video/x-raw-yuv,format=\(fourcc\)I420 ! theoraenc ! oggmux ! filesink location=output.ogg I get an ogg file with only one frame (processing time 9 s). Streaming the files to the screen, i.e. your suggestions > gst-launch multifilesrc location=test%05d.png caps="image/png,framerate=25/1" ! pngdec ! ffmpegcolorspace ! autovideosink works fine. So I assume theoraenc or oggmux is not called properly/broken. If I use diracenc and avimux it works fine as well.
