A threshold of 1 is sufficient for simple_dump_cut.webm, 10 is used
just to be sure the next truncated file doesnt cause the same issue
Obvious alternative fixes are to simply accept that the file is broken or to
write some advanced error concealment or to
simply accept that the decoder wont stop
currently, the layer number is at the beginning of the .model file,
so we have to scan twice in python script, the first scan to get the
layer number. Only one scan needed after put the layer number at the
end of .model file.

the info can be saved in dnn operand object without regenerating again and

and it is also needed for layer split/merge, and for memory reuse.

Main image data in DNGs is usually comprised of tiles, each of which is a
Huffman-encoded lossless JPEG.
Tested for ljpeg regressions with:
`ffmpeg -f lavfi -i testsrc=d=1 -vcodec ljpeg test.avi`
`ffmpeg test.avi out.avi`
The modified code in ljpeg_decode_rgb_scan runs without issues.

Some JPEGs [1] have incorrect DHT entries that map 2 codes to
the same value.
The second (last) mapping does not ever actually appear in the
code stream, therefore ignoring any mappings after the first one
fixes this.
Without this, an "mjpeg_decode_dc: bad vlc: 0:0" error is thrown.

In an image [1], the height was equal to the tile length (full-height
tile) and after `height % tile_length` was applied to them with the
current code, it resulted in the operating tile_length to be 0. This

Hi all,
FFmpeg has been accepted again for a booth at the LinuxDays 2019 in Prague,
Czech Republic from October 5th to 6th!
Like last year, we hope to have a great conference with many users and fellow
open-source projects attending! Find detailed information here:

No, but AFAIK it is for all devices which support SDI. Generally it's
the older analog capture devices which don't support it.

Also, ensure no false positives when determining DNG bayer images, by
setting them in tiff.c instead of relying on a heuristic. There's no
way to determine this just from the JPEG data, so we have to pass this
information from outside the MJPEG decoder.
