Dear list,
I've 109 png or svg files. I create a video from it. But the video is not
zoomable. I cannot zoom in or out with my mouse. Is it possible to activate
the zoom option for the video.
Best wishes
Abdulla

This mailing list (ffmpeg-devel) is only
zmbv has only one function for decoding intra frames, namely
decode_intra. This can be used to simplify the process of choosing the
right function pointer.
This also removes spec-incompliant conversions between function pointers
and pointers of type void * and thereby fixes the warning "ISO C

This patches fix several bugs in the mpjpeg demuxer.
I think it is not possible to create a fate test for patch 2/3 (and 3/3?),
as the bugs rely both on the stream and on the HTTP header announcement, so
one would need to simulate a web server.

According to RFC1341, the multipart boundary indicated by the
Content-Type header must be prepended by CRLF + "--", and followed
by CRLF. In the case of strict MIME header boundary handling, the

A side effect is that this coincidentally breaks
The string matching function's return value was evaluated incorrectly.

Not only the first, but each latest chunk must be cached to allow

They are not allowed outside of functions. Fixes the warning
"ISO C does not allow extra ‘;’ outside of a function [-Wpedantic]"
when compiling with GCC and -pedantic.

Silence detection can only be set with the -algorithm 3 option, so
update the documentation.

I used that value somewhere during patch development, but I eventually
settled on -1, because that "start_pts" and "end_pts" are using some other
units, not the unit used by pkt->pts.
So I wanted to make a distinction. Though a possibility of negative
timestamps didn't come to me, so I probably
