[FFmpeg-devel] Question about HEIF/HEIC support

2020-09-26 Thread Tom Needham 
Hello

I have spent some time researching the possibility of adding demuxing and
muxing support for the HEIF image format into FFmpeg when I came across
this GSOC project from last year.
https://summerofcode.withgoogle.com/archive/2019/projects/5632663078043648/.
Although it appears the resulting work was never sent back to FFmpeg.

After doing a bit more digging I found the Github repository of the author
of the original work
https://github.com/Swaraj1998/FFmpeg/commit/9a885cddb3550ab863a60d02c5fb78e4ae206cf1
and there is a commit there that seems to contain the required code for
HEIF demuxing, I have compiled that branch locally and it seems to handle
all the samples I could throw at it.

Was there a reason this work was not pushed back to FFmpeg? If it is just a
matter of updating the patch to work on the latest master. I would be happy
to help out.

Thanks
Tom

2020-09-16 Thread Tom Needham 
Is there a known alternative for windows which provides the same features
of Zeranoe? If not I would be interested in setting something up but I'm
having trouble building all the external libs for windows. If anyone has
any tips or guidance please let me know.

Thanks

Re: [FFmpeg-devel] .NET video processing with FFMPEG

2020-09-16 Thread Tom Needham 
There is a great wrapper for invoking FFmpeg in .NET available here
https://github.com/tomaszzmuda/Xabe.FFmpeg/ however it does not support
calling the C API directly. I am not aware of any tools or libraries that
have this functionality.

Thanks
Tom

[FFmpeg-devel] [PATCH V4] avformat: Add Dynacolor MVC Demuxer

2020-05-16 Thread Tom Needham 
Please ignore my previous email as it was sent in error.

This demuxer adds support for demuxing files in the Dynacolor format
such as the sample located at:

http://samples.ffmpeg.org/camera-dvr/dynacolor/dynacolor-camera-sample

However some decode errors are showing on the resulting MPEG4 stream.
I don't know whether this is a bug with the demuxer or the file as there is 
only one sample
but the output results in a 8 second mp4 file that is playable in VLC media 
player.

I believe that i have addressed the comments that I recieved in the previous 
review.
Also i have managed to improve the efficiency of the demuxer and also made the 
probe function more useful.

Thanks
Tom

[FFmpeg-devel] ffmpeg.org down

This is probably off-topic for this mailing list, but I wasn't sure where
to post this.

ffmpeg.org seems to be down for me at the moment and all connections are
timing out, is there any in progress maintenance/issues currently?

[FFmpeg-devel] [PATCH] avformat: Add Dynacolor MVC Demuxer

2020-03-22 Thread Tom Needham 
This demuxer adds support for demuxing files in the Dynacolor format
such as the sample located at:

http://samples.ffmpeg.org/camera-dvr/dynacolor/dynacolor-camera-sample

However, some decode errors are showing on the resulting MPEG4 stream.
I don't know whether this is a bug with the demuxer or the file as there is
only one sample
but the output results in a 1 second mp4 file that is playable in VLC media
player.

Re: [FFmpeg-devel] [PATCH] avcodec: Implement DM PAR Muxer/Demuxer

2019-07-08 Thread Tom Needham 
Hi Paul

The only windows player I am aware of can be downloaded from here.

https://www.dedicatedmicros-support.com/software_release/download.php?file=5357

Also, there is a tool that directly converts these PAR files into H264
format which can be obtained from here.

https://www.dedicatedmicros-support.com/software_release/download.php?file=3344

And finally the library I used to create the wrapper can be downloaded from
here.

https://www.dedicatedmicros-support.com/software_release/download.php?file=3347

Thanks
