[FFmpeg-devel] [PATCH] avfilter/codecview: Enable QP visualization for H.264

[Timothée]

Context from the first version : Subject was "avcodec/h264: fixed qp table attach for h264"


> Here is a patch where I fixed the attach of per-macroblock qp tables for
> H.264. It was implemented for MPEG2 so I have only extended it.
>
> I tested the functionality with the codecview filter using the following
> command: `./ffmpeg -export_side_data 4 -i input.mp4 -vf codecview=qp=1
> output.mp4`

Here is the new version of the patch.

I have remove the unnecessary line in qp_table.h and changed the commit 
message.
