Hi Michael,
I think I know where the misunderstanding could be.
The main changes in my patch are:
rematrix.c:389 and rematrix_int.c:36:
Before:
int nb_in = av_get_channel_layout_nb_channels(s->in_ch_layout)
After:
int nb_in = s->in_ch_layout != 0
? av_get_channel_layout_nb_channels(s

Hi Marton et al,
I am revisiting this now that I have access to the BlackMagic DeckLink Duo
again. I see what made it into master and had a few questions.
1) Can you please explain more about storing the timecodes as side packet data
in each video packet? Basically is there some convention amon
Plan to push in a day if no objections.

Ping - What about this one? I tested it with about 20 files and it works
perfectly
for all of them - except one which has tag/padding. In its case, playback
quality
is virtually the same as without the patch, i.e. no harm done.
Cheers, Karsten

Ancillary data can carry various side data that can't be transmitted in
bitstreams. For now, this struct includes interlaced field flags and
the must be attached to an AVPacket as side data.

This codec is already capable of depacking some combinations of pixel
formats and depth as defined in the RFC4175. The only difference between
progressive and interlace is that either a packet will contain the whole

From: Damien Riegel
In order to handle the interlaced formats, the demuxer has only a few
things to do:
- parse the SDP correctly and propagate the information
- check the field bit in the RFC4175 header, and pass that information
to the decoder
In interlaced mode, received data only consis

The slow down happens with all MP4 and MOV files, but if you just want
a long sample that makes it obvious, yes ffmpeg can make it.
Probably something like (untested):

Some performance number make sense for the commit message imo.
