Re: [linux-sunxi] Re: PoC tvin2jpeg_h264 with veisp scaling

I'm glad to hear that. I hope that you will find out what the cause is. However, before ioctl reset, sometimes i had some strange glitches in h264 decoded picture when work simultaneous with h264enc. Some small blocks in the picture was wrong (usually upper left part of picture) color or

Re: [linux-sunxi] Re: PoC tvin2jpeg_h264 with veisp scaling

Thank you Manuel! I managed to make a H264 decoder and it works fine. Now i can run all four operation simultaneous but... Known bug: For now the app can play source with 'num_ref_frames' greater or equal to 1 but if i try to play source with 'num_ref_frames: 3' simultaneous with 264Enc the

Re: [linux-sunxi] Re: PoC tvin2jpeg_h264 with veisp scaling

Hi again, I just wanted to make PoC test simultaneous tasks for my future project and to show others how much this platform is powerful. I need tvin, h264-jpeg encoder+scaler and decoder. Maybe i do not need all four operation simultaneous, but for now i have two cases: -

Hello Manuel, I just added hw JPEG decoder in my apps. Now i can do simultaneous h264 encoding, jpeg encoding and jpeg decoding with just ~20% CPU and 25 fps. How app works: Take frame from camera tv-in CVBS 720x576, show it on display by sunxi display engine in smaller resolution 542x359

Have you tried to port it (JPEG encoder) to H3? On Thursday, November 24, 2016 at 10:20:38 AM UTC-2, Milos Ladni wrote: > > Hello, > > This is yet another Proof of Concept analogue TV decoder (TV-IN) and > hardware accelerated H264-JPEG encoder with VEISP scaling for sunxi. > This example
