I even had idea to use PS2 emulator to check (DVD video supposed to
work there since some time)
but ran into qt6 being build dependency ... so I shelved this idea for now
Thank you

At least this pdf br
Cirrus Logic application note from 2001 that mentions 32khz
pcm operation. Yet it looks more like external amplifier/decoder part, not
something integrated into dvd player itself? (input stream via S/PDIF)

We tried to update cinelerra-gg to ffmpeg 7.1 and ran into two problems:
First, vf_scale now declares dynamic input and was filtered out by code
in cinelerra/pluginfclient.C
int flag_mask = AVFILTER_FLAG_DYNAMIC_INPUTS |
AVFILTER_FLAG_DYNAMIC_OUTPUTS;
if( filter->flags & flag_mask ) return AV
I tried to trivially add qsv/mediacodec decode to cinelerra-gg, but
discovered that I can't use it like vaapi/vdpau/cuda because (?)
qsv/mediacodec not listed in
ffmpeg/libavcodec/hwconfig.h
and (for h264) in
ffmpeg/libavcodec/h264dec.c
so on decoding I get (in termux, cingg compiled with system

Hello.
Recently I teached cinelerra-gg to use qsv encoders in ffmpeg (libavcodec)
and some test were working but some not.
We nailed it down to top-field first material, like HDV files. bff files
like consumer version of DV and progressive worked fine.
I looked at source and ... I thought cond
Otherwise it just feels like random snapshot everyone downstream must adapt
to.
Also, PLEASE add API changelog in future release announcements on website,
I want to see what broken in each release. Right now it looks like only
"positive" end of news openly publicized. Be honest, post other end of
19 matches
