I think, I can do that easily using DirectShow library, by reading the .avi/.asf file using SourceFilter, connect it to Microsoft H.261 Video Codec, .. (then ? I dont know where my graph should go after this ;) but I never could connect any filter to Microsoft H.261 Video Codec's input pin .. I have tried many kind of YUV as its input (I420, YV12, YUY2, YVYU, UYVY) ... is there some settings should be done before connecting any filter to Microsoft H.261 Video Codec ? what requirement for using that codec in our DirectShow application ? any programmer reference for that ? thanks alot, On Fri, 28 Nov 2023 17:00:17 -0800 "Gary Sullivan" wrote: > Also, one subset of H.263 is its baseline profile.

As I said it is targeted only for video and audio support. One of the intersting solutions would be to use Quicktime 6.4 API to perform decoding and demultiplexing. My first move was to evaluate how Quicktime behaves itself regarding .mp4 and .3gp files. So I went to Envivio and Philips and downloaded their video samples (including interoperability samples). My current success rate is only that 50% of the files play correctly. Does anybody could give more details about issue ? Is Quicktime late regarding interoperability or are the Envivio and Philips samples outdated ? My second question is perhaps more [MP4-discuss]-oriented but nevertheless since it regards Quicktime, I'll ask it there. As far as I know, usage of MPEG-4 involves licensing fees to be paid to MPEG-LA. If I use the Quicktime API including MPEG-4 and 3GP support, do I get it for free since I suppose Apple already pays for the license ?

You can refer to media content directly from a track in another mp4 file. To refer to a track just append #video (or #audio if its an audio track you want) after the file name e.g. "myfile.mp4#video". If there is more than one track of a given type you can do "myfile.mp4#video(2)" which will use the second video track it finds. Hence "myfile.mp4#video" is equivalent to explicitly specifying the first video track using "myfile.mp4#video(1)". You can find other posts about using #video etc on the alphaworks forum for the IBM Toolkit for MPEG-4. In XMT-O
