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

I was testing our libtheora encoder/muxer after updating to libtheora 1.2.0
and noticed that ffmpeg complains about "(non)keyframe not correctly marked"

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

Hi.
I still wish you put some time in making more accurate web changelog, with
detailed (with git commit links) API changes, and new/closed bugs and
regressions since last release (a bit like wine project does this part for
