Difference with ffplay - Githubissues

cascarpato commented 10 years ago

Hi all, i have tried to use QtAv to show a video from an IP Cameras but the result is very different compared with ffplay. The QtAv Video is slower and not fluid and present more artefacts and a degraded Image. With ffplay there are no problems: the video is fluid and clean. The only log from QtAv adn ffmpeg is:

[ffmpeg: h264]: Current profile doesn't provide more RBSP data in PPS, skipping. Any Ideas?
