Hi Ross, hi people, I am new to this list.
I have been developing a rtsp streaming client application based on the openRtsp test program for a couple of time now. I use the AviFileSink to write an mpeg4 stream from a camera to a file. Files can be played by all desired players, but we would like to improve the seeking and reverse playing functionality. Bad seeking performance would be, slow framewise backward transport in virtual dub, or unreliable jumps and frameswise move in MCI-based video players (that would be the applicational target of the generated files). Analyzing the .avi files show, that no index list is written, virtual dub gives the following message: index not found or damaged; keyframe flag reconstruction was not specified in open options and the video stream is not a known keyframe-only type. Seeking the video may be extremely slow Now, I am no specialist for the avi-file format, but my first attempt was to add an index with another software, for example virtual dub. I succeeded in creating the list, but it did not give satisfiying results on seeking performance. Comparing the files with other files that provide good seeking performance did not show any structural indifference. Is anyone familiar with my problem? Do I concern the right issues on solving that problem, or is anything about the construction of the avi-header, flags etc. of importance. Could it even be a question of the video-codec? Thanks for help in advance, Greetings, Max.
