Hi,
I just got an imate Jasjar Pocket PC and wanted to show off some videos on it. Its got WM5 on it, and I have installed TCPMP v0.72RC1 with plugins flv 0.3, ffmpeg 0.72RC1 and ac3 0.72RC1. My encodes are xvid only as they are meant exclusively for the standalone box, but I read TCPMP did H264 so decided to try x264 for the PPC.
I used GKNOT and x264-468 for encoding the 4 minute final motercycle chase sequence from final fantasy VII advent children and I followed the doom9 x264 guide for reference. I encoded at 320x176 and 23.976 FPS, the bitrate was I guess 258 kbp for a 10MB file. Since this was my very first experience with x264, the options were rather daunting and I decided to go mainly with the defaults while opting for max quality values in the Analysis section which might have been overkill. The encode (which took about half an hour on my slowass machine) played back perfect on my PC, here I'd like to add that x264 is reeaally amazing, I mean I watched this puny res file full screen on my PC and WOW, it was that good.
When I opened it in TCPMP on the PDA, the sound played fine but the video didn't, it didn't stutter, it just played a few frames, then froze, when I manually seeked forward, it would again play a few frames, then froze again but the sound still played fine, in the media info window, it showed a whole lot of dropped frames, which means I went overboard while setting the x264 options. Now the strange thing is that when I played the same file in the benchmark mode fullscreen, it played fine, both video and sound without even a stutter.
My question is whether anyone has had experience with encoding H264 for the pocketpc and would like to share her/his
technique. All I know about encoding, I've learned at this forum and I'd appreciate any further help with this problem.
