v2 v3 718 718 * The CODA driver requires CMA memory for buffers when it is used. Make sure to provide the kernel with enough CMA memory with the kernel command-line (ie 'cma=64M' for 64MB which should be enough) 719 719 720 Note that the following examples assume you are using raw video encoded files, not container formats used for mimxed multimedia types (audio + video) such as ogg, avi, or mov (Quicktime). For information on de-muxing container formats see [ wiki:gstreamer/multimedia]720 Note that the following examples assume you are using raw video encoded files, not container formats used for mimxed multimedia types (audio + video) such as ogg, avi, or mov (Quicktime).

You can search for your specified one by running a similar search: {{{gst-inspect-1.0 | grep enc}}}. 803 803 804 Note that each encoder has its own limits on the samples it accepts (S16LE, S24LE etc). You can find the formats accepted via {{{gst-inspect-1.0 <element>}}} and you can use the [#audioconvert {{{audioconvert}}}] element to convert audio samplerate / bitwidth / format (via software algorithms) as needed between two elements.804 Note that each encoder has its own limits on the samples it accepts (S16LE, S24LE etc).
