[vlc-devel] [PATCH 0/3] OMX: improve performance

[Thomas Guillem]

As discussed with Martin here:
https://github.com/tguillem/vlc/commit/7404e3065705107d5f87f63ed95c86cd16fe0633

I propose a set of 3 patches that should improve OMX performance.

With a Samsung Galaxy S3 and with HwBuffer activated (not in this set of
patches), I win a lot of FPS: from 1fps to 25fps.

The third patch is a bonus, only cosmetic, I don't know if you want it, but it
make the DecodeVideo function clearer:

...
    /* Take care of decoded frames first */
    if( DecodeVideoOutput( p_dec, &p_sys->out, &p_pic ) != 0 )
        goto error;

    if( DecodeVideoInput( p_dec, &p_sys->in, pp_block, &b_reconfig ) != 0 )
        goto error;

    /* If we don't have a p_pic from the first try. Try again */
    if( !b_reconfig && !p_pic &&
        DecodeVideoOutput( p_dec, &p_sys->out, &p_pic ) != 0 )
        goto error;
...

Regards,
