Video freeze while decoding AVC H.264 RTSP stream

[caraprince]

Dear all,

I'm implementing an RTSP server which distribute DVB-T to PC or hand-held devices. The stream can be decoded successfully by VLC on PCs. While streaming to VLC on android or iOS, video always freezes on first frame, but audio plays well. I think the video is OK cause if I stream it by HTTP, VLC plays well. The video format is AVC H.264 1080i. I captured the RTP packets by using Wireshark and uploaded it to the following link.

Is there anyone that can help me to check what the problem is? Thanks a lot.

Hello,

You should generate a playback log so that we can see what is going on under the hood.

Hi ,

I am also having issues with the latest vlc version(0.9.9).The videos are staggering a lot while playing Full HD videos (1080 p) on samsung s3,this issue is only when playing the videos in the landscape mode no problem in portrait mode.I created a small video player app using the libvlc from the github and the app created by me also having this exact same issue ,the only error log I am getting is "core video output: picture is too late to be displayed (missing 117 ms)" .I disabled the hardware overlay of the phone and I tried to play the same video and it was playing fine but I don't want to disable that.Any ideas?

PS : There are no problems with videos having resolution 720 p and lower.

Regards

It might be an issue with your phone's hardware acceleration.

My problem is solved in VLC 0.9.9 for Android. I don't know why.
But there is a new problem on VLC 0.9.9. While I stream h264 1080p video to VLC, a hardware acceleration error occurs on Asus Nexus 7 2013. The following is the catlog. It does not happen on my other devices.

That is an internal problem with your device's hardware decoder.
