Hi
There may be a bug for .mp4 reader.
On decoding some ntsc mp4 files with my h.264 codec, from actvx I received,
avctx->framerate.den is 100
avctx->framerate.num is 2997
avctx->pkt_timebase.num is 1

Hi
This is the fixed version of this patch that follows the way other
companies do on supporting FFmpeg.
1>Put library mvm264 to the nonfree list in configure
2>Remove calling to dlopen
Please review.

Hi
Matrox card is very similar to cards from other companies in terms of
accesses.
I suggest that we should differentiate hardware codec and software codec.
Hardware codecs are very strong help to FFmpeg for high resolution video
encoding and decoding like 4k. though gradually software codec w

It seems FFmpeg supports reading all kinds of mxf files from Sony and
Panasonics. it's very good to find that FFmpeg can support Sony XAVC
QuadHD files and find the essence data is actually H.264.
Our customers have a lot of high data rate mxf files from Sony and

On transcoding from 1080p .ts files to .mp4 files with my m264 codec,
audio of the output .mp4 files stutters.
We found audio of the stuttering files is vbr.
I did not set aac encoding bitrate. somehow it becomes vbr when I use my
m264 codec on transcoding 1080p files.
It works well for 10
Hi Jean-Baptiste
Sorry for the complexity and confusion to so many people involved on
this new patch.
We have been working on this for 4 months because some of our big

Hi
It seems ffmpeg can only generate AVCC box if I set extradata in my encoder's
init function, it does not take the extradata if I make it in receive_packet
function.
But I don't have sps and pps when the encoder's init function is called. I only
can get it when I get first encoded frame.

Hi Carl
Matrox M264 is similar to other hardware codecs.
I saw amf_load_library and nvenc_load_library in ffmpeg.
Matrox M264 is the same.
We got a lot customers using ffmpeg and they want to use Matrox M264 to do
transcoding.
Thanks a lot.
Yufei.

Hi Tomas
Thanks for the review.
My codec is a hardware codec, it depends an dynamic library that goes
with the M264 card.
The way it works will be:

3>Call ffmpeg with codec option of m264.
