[Libav-user] avpicture_fill

[Neil Menne]

avpicture_fill is not filling in the linesize or data as expected. I could
really use some help here.

See the following:

AVFrame *output_frame = avcodec_alloc_frame();

output_size = avpicture_get_size(AV_PIX_FMT_YUV420P,
                                               640,
                                               480);

uint8_t *output_buffer = (uint8_t*)av_malloc(output_size);

avpicture_fill((AVPicture*)output_frame,
                   output_buffer,
                   AV_PIX_FMT_YUV420P,
                   640,
                   480);

... later ...

sws_scale(...);

Outputs: [swscaler @ 0x912dd60] bad dst image pointers

Thanks for your time!
