22 | * How to use this decoder: | ||
23 | * SVQ3 data is transported within Apple Quicktime files. Quicktime files | ||
24 | * have stsd atoms to describe media trak properties. A stsd atom for a | ||
25 | * video trak contains 1 or more ImageDescription atoms. These atoms begin | ||
26 | * with the 4-byte length of the atom followed by the codec fourcc. Some | ||
27 | * decoders need information in this atom to operate correctly. Such | ||
28 | * is the case with SVQ3. In order to get the best use out of this decoder, | ||
29 | * the calling app must make the SVQ3 ImageDescription atom available | ||
30 | * via the AVCodecContext's extradata[_size] field: | ||
31 | * | ||
32 | * AVCodecContext.extradata = pointer to ImageDescription, first characters | ||
33 | * are expected to be 'S', 'V', 'Q', and '3', NOT the 4-byte atom length | ||
34 | * AVCodecContext.extradata_size = size of ImageDescription atom memory | ||
35 | * buffer (which will be the same as the ImageDescription atom size field | ||
36 | * from the QT file, minus 4 bytes since the length is missing) | ||
37 | * | ||
38 | * You will know you have these parameters passed correctly when the decoder | ||
39 | * correctly decodes this file: | ||
40 | * http://samples.mplayerhq.hu/V-codecs/SVQ3/Vertical400kbit.sorenson3.mov | ||
