Yes; however, it doesn’t work for *all* H.264-in-MPEG-Transport-Stream video files - including, unfortunately, the "bipbop-gear1-all.ts” file. In particular, it relies upon a SPS (Sequence Parameter Set) NAL unit appearing shortly before each 'I-frame’; see http://lists.live555.com/pipermail/live-devel/2010-December/012976.html I have, however, just uploaded two H.264-in-MPEG-Transport-Stream video files (and their corresponding ‘index files’) for which the trick play mechanism works OK. See the files “rango.ts” and "test008.ts” (and the corresponding “.tsx” index files) that are now online at: http://www.live555.com/liveMedia/public/h264-in-mp2t/ Ross Finlayson Live Networks, Inc. http://www.live555.com/ _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel
