I have the developers version of ffmpeg lib and include files in with my shared ffmpeg file. How do I get it to work ?

I have included -lmingw32-libarchive and -lsdlmain to avoid winmain16 error, should I do something else ? How to avoid deprecated error ?

Revision 0d8723f8d5 : Make "good" quality 2-pass vpxenc encoding default Currently, the best quality

19 août 2013, par Deb Mukherjee

Changed Paths :
Modify /test/encode_test_driver.cc

Modify /test/error_resilience_test.cc

Modify /vp9/vp9_cx_iface.c

Modify /vpxenc.c

Make "good" quality 2-pass vpxenc encoding default

Currently, the best quality mode in VP9 is not very well developed,
and unnecessarily makes the encode too slow. Hence the command line
default is changed to "good" quality. Also, the number of passes
default is changed to 2 passes as well, since 1-pass encoding is
not very efficient in VP9.

Besides, a number of VP9 defaults are set to the currently
recommended settings. With these changes, vpxenc
run with —codec=vp9 —kf-max-dist=9999 —cpu-used=0 should
work about the same as our borg results.
Note when the —cpu-used=0 option is dropped there will be a slight
difference in the output, because of a difference in the cpu-used
value for the first pass. Specifically, the default when unspecified
is to use cpu_used=1 for the first pass and cpu_used=0 for the
second pass. But when specified, both passes will use the cpu-used
value specified.

Note that this also changes the default for VP8 as being "good"
but other options stay unchanged.

How to read video frame by frame in C# .NET Framework 4.8 ?

27 septembre 2022, par Brendan Hill
I need to read a video file (.mkv format, h264, 1280x720) frame by frame for video processing.




I am stuck with .NET Framework 4.8 due to dependencies.




Having tried Accord.net VideoFileReader I am unable to read them due to :



```
[matroska,webm @ 0000024eb36e5c00] Could not find codec parameters for stream 0 (Video: h264, none(progressive), 1280x720): unspecified pixel format&#xA;Consider increasing the value for the &#x27;analyzeduration&#x27; and &#x27;probesize&#x27; options&#xA;Assertion desc failed at src/libswscale/swscale_internal.h:674&#xA;
```



Unfortunately Accord.NET does not give me much control over the ffmpeg request and the project seems to have died (and .NET Framework has died (and C# has died)).




What are some alternatives which would allow me to read a .mkv file in h264 format frame by frame ?




NOTE - FFmpeg.NET does not seem to support getting frame bitmaps ; neither does MediaToolkit :(




NOTE - this page has the same problem (last comment 2020) but no resolution :( https://github.com/accord-net/framework/issues/713
