I'm using Wowza Media Server 2 Perpetual 2.2.4 build27452, and I have come across several mp4 files in our collection (encoded from DVD using Handbrake) that only produce sound, no video. I'm using JW Player, as outlined
here. I tried re-encoding the films, still using Handbrake as it's our only encoding software, but the problem persists. The problem also appears when I use the Adobe Flash player, as outlined
here. These same mp4 files play fine when streamed from Helix server to QuickTime player, so I know the files aren't corrupt. Any ideas?
We stream video from Wowza server. Our player lets user to choose video quality : HD, HQ, SD, all in H264 mp4 encoded with the same software. HD and HQ video plays perfectly but SD (500Kbps encoding) sometimes (may be 1/5 times) play audio without video.
Any clue to help to solve or find a way to solve this problem?
