Some m4a files with an image-track don't play An example file can be found at: http://www.darkhorizonsradio.com/podcasts/shows/Dark_Horizons_080510.m4a (138MB) Miro 3.0.3 hangs after the message: ** Message: don't know how to handle video/x-gst-fourcc-, width=(int)600, height=(int)600, framerate=(fraction)1/3, pixel-aspect-ratio=(fraction)40/37 Rhytmbox 0.12.6 also hangs with: Rhythmbox-Message: Missing plugin: gstreamer|0.10|rhythmbox|video/x-gst-fourcc- decoder|decoder-video/x-gst-fourcc- Rhythmbox-Message: Automatic missing codec installation not supported (helper script missing) I'm running Gentoo x86, installed gstreamer-packages: gstreamer-0.10.29 gst-plugins-good-0.10.22 gst-plugins-ugly-0.10.13 gst-plugins-base-0.10.29 gst-plugins-bad-0.10.18 gst-plugins-fluendo-mpegdemux-0.10.15 gst-plugins-flac-0.10.22 gst-plugins-theora-0.10.29 gst-plugins-musepack-0.10.18 gst-plugins-lame-0.10.13 gst-plugins-gconf-0.10.22 gst-plugins-v4l2-0.10.22 gst-plugins-libmms-0.10.18 gst-plugins-faad-0.10.18 gst-plugins-gio-0.10.29 gst-plugins-vorbis-0.10.29 gst-plugins-pango-0.10.29 gst-plugins-ogg-0.10.29 gst-plugins-taglib-0.10.22 gst-plugins-dvb-0.10.18 gst-plugins-cdparanoia-0.10.29 gst-plugins-speex-0.10.22 gst-plugins-meta-0.10-r4 gst-plugins-x-0.10.29 gst-plugins-alsa-0.10.29 gst-plugins-oss-0.10.8 gst-plugins-jpeg-0.10.22 gst-plugins-soup-0.10.22 gst-plugins-mad-0.10.13 gst-plugins-esd-0.10.22 gst-plugins-libpng-0.10.22 gst-plugins-xvid-0.10.19 gst-plugins-gnomevfs-0.10.29 gst-plugins-ffmpeg-0.10.9 gst-plugins-mpeg2dec-0.10.13 gst-plugins-v4l-0.10.29 gst-plugins-a52dec-0.10.13 gst-plugins-x264-0.10.13 gst-plugins-resindvd-0.10.18 gst-plugins-dvdread-0.10.13 gst-plugins-xvideo-0.10.29 gst-python-0.10.17
The audio plays fine for me in this file with git version. This file has 4 traks, one for audio, 2 for text and 1 for images. The images one has lots of stsd entries (qtdemux doesn't handle this, I had a patch around to allow this, but this is just a first step). When playing it in quicktime it shows the images while playing the audio, and it builds a index with names of the parts of the audio (tracks? chapters?), each part has its own image.
Works fine now. Note sure when it was fixed.
