VLC 0.8.6a on Davinci Platform - Poor A/V Quality

[amareshram]

Hi,

I have ported the VLC-0.8.6a on TI's Davinci Platform. I am able to play mpeg-2 a/v media file but the audio/video quality is not good. When I run it with trace, I observer following messages:

[00000254] main video output warning: late picture skipped (-232682)
[00000253] main audio output debug: PTS Out Of Range (22271), dropping buffer

Repeated frequently.

It gives me an impression that audio & video buffers are dropped frequently and hence the poor quality. can somebody help me to resolve it?

regards/Amaresh

Is the CPU usage maxed out when you play the file with VLC? (btw, feel free to submit a patch to the vlc-devel@videolan.org mailing list so we can include your port in future VLC releases)

no.

and it is the only application running on platform.
platform spec. is as follows:

CPU speed: ~233MHz
RAM: 64MB DDR

While going through the source code, I observe that some comparision is made out based on some #define provided in vlc_config.h for audio/video. I am planning to play with them but it will be nice if someone inform me that how these values has been derived.

Did you use the DSP side of Davinci platform
