DASH: Parse MIME type, width and height into Format for image AdaptationSet #9500
Description
Hello guys, I want to extract the width, height, and value of the image from the following manifest.
<AdaptationSet id="3" mimeType="image/jpeg" contentType="image">
<SegmentTemplate media="$RepresentationID$/tile_$Number$.jpg" duration="100" startNumber="1"/>
<Representation bandwidth="12288" id="thumbnails_320x180" width="3200" height="180">
<EssentialProperty schemeIdUri="http://dashif.org/thumbnail_tile" value="10x1"/>
</Representation>
</AdaptationSet>
I have referred to #8577 as an example but it only works for mimeType="video/mp4".
code for image/jpeg:
if("image/jpeg".equals(mimeType)){
Representation.MultiSegmentRepresentation multiSegmentRepresentation = (Representation.MultiSegmentRepresentation) representation;
Log.d("format.width" , String.valueOf(multiSegmentRepresentation.format.width));
for(int l = 1; l < multiSegmentRepresentation.getSegmentCount(periodDurationUs); l++) {
Log.d("sprite_uri" , String.valueOf(multiSegmentRepresentation.getSegmentUrl(l).resolveUri(representation.baseUrls.get(0).url)));
}
return;
}
result:
2021-09-28 17:34:23.146 25820-25820/com.example.exoplayerdemo D/format.width: -1
code for video/mp4:
if("video/mp4".equals(mimeType)){
Representation.MultiSegmentRepresentation multiSegmentRepresentation = (Representation.MultiSegmentRepresentation) representation;
Log.d("format.width" , String.valueOf(multiSegmentRepresentation.format.width));
Log.d("format.height" , String.valueOf(multiSegmentRepresentation.format.height));
return;
}
result:
2021-09-28 17:52:07.574 23252-23252/com.example.exoplayerdemo D/format.width: 1024
2021-09-28 17:52:07.574 23252-23252/com.example.exoplayerdemo D/format.height: 576
Any suggestions to parse this thing in exoplayer?
