[Libav-user] Help decoding error messages

jonsmirl@gmail.com
I'm trying to decode the video coming from a Hi3516 based RTSP
security camera. I've set the probe buffer upto 20MB and it still did
not find the codec parameters.

This is a fixed camera so I can use Onvif to query the parameter and
set them, but what parameters is it looking for?

This appears to be the fatal error:
W/ACodec: cannot describe color format 0x13 = 19 with stride=0 and sliceHeight=0

Re: Help decoding error messages

jonsmirl@gmail.com
The solution to this is to set the image width/height manually into
the decoder context. To work around this failure "Could not find codec
parameters for stream 0 (Video: h264 (Main), 1 reference frame,
none(progressive)): unspecified size"

avctx->width = 1920;
avctx->height = 1080;
