[FFmpeg-devel] [PATCH] avcodec/on2avc: use the matching AVTX context for the 512 sized iMDCT
Improves the audio corruption regression caused by
6ba0aa1770ba29eb4126c6a706f6b0cd3809648f reported in ticket #10029.
There is still however a noticable audio glitch, so the FFT conversion to AVTX
probably also needs some modifications.

Actually, looking at it, the WINDOW_TYPE_EXT7 branch, something
weird's going on there as well:
- c->mdct.imdct_half(&c->mdct, buf, in);
+ c->mdct_fn(c->mdct, buf, in, sizeof(float));
The original misused the context. Maybe this
should be both half as well?

probably, yes
I think you know the spec better than i do, so you can probably pick
the tightest bound quicker ...
can you submit a patch doing that ?

Actually, looking at it, the WINDOW_TYPE_EXT7 branch, something
weird's going on there as well:
- c->mdct.imdct_half(&c->mdct, buf, in);
+ c->mdct_fn(c->mdct, buf, in, sizeof(float));
The original misused the context. Maybe this
should be both half as well?
I thought that is just the old API where you have to use the imdct_half
function to get the useful half-sized IMDCT. But the old code really means
to use the 11-bit context to calculate 1024 samples not the 10-bit one
confusingly called c->mdct_half to calculate 512 samples.
Regards,
Marton

The first proposal was a simple demuxer in libavformat which used libsoapy That was objected to The second proposal was a simple demuxer in libavformat and a input device in libavdevice which used libsoapy That was objected to The third proposal moved the simple demuxer and input device to libavradio That was accepted, but then the build system changes where objected to so we cannot link to that The forth proposal moves the simple demuxer and input device back out of libavradio (as we cannot link to it without build system changes) this was not objected to but the unrelated bugfixes after that where objected to There is the general theme that a intermediate API should be added but with apparently noone who subscribes to this suggestion knowing or caring how to do that. libsoapy is the external library used by the input device code on top of the hw independant demuxer code. <-- this is a terse description of what we have ATM Is what you ask for, that I develop a general purpose SDR library ? Because i cannot think of anything else that could reasonbly be meant by "API" here. Now please think about this for a moment i should write a general purpose SDR library to be "allowed" to add a SDR module to ffmpeg ? You compared this to libswresample and libswscale but a general purpose SDR library is more like a general purpose multimedia library than a general purpose audio resampler. I dont think demanding i write a general purpose SDR library to be "allowed" to add a SDR module to ffmpeg has a majority behind it. This is not what people where thinking off when they suggested an API If its not about writing a general purpose SDR libraray, then what exactly is the suggestion ? And also does that make sense ? thx [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Observe your enemies, for they first find out your faults. -- Antisthenes signature.asc Description: PGP signature ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
Re: [FFmpeg-devel] What is FFmpeg and what should it be
Your attempts to troll other developers to work on SDR/AVRadio is flawed and disrespectful to other FFmpeg people. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
[FFmpeg-devel] [PATCH v3 0/1] configure: Set WIN32_LEAN_AND_MEAN at configure time
Thanks Martin for the suggestion, I've implemented it in this version. As for the changes to os_support.c, the removal was intended to avoid duplicating the logic that already exists in os_support.h. I've kept it in this version for consistency. L. E.

[FFmpeg-devel] [PATCH v3 1/1] configure: Set WIN32_LEAN_AND_MEAN at configure time
Including winsock2.h or windows.h without WIN32_LEAN_AND_MEAN cause bzlib.h to parse as nonsense, due to an instance of #define char small in rpcndr.h.
