this one decodes correctly when you force bitexact decoding:

This patch set should fix decoding of the SA10135.vc1 test file to make it

Thanks for letting me know about this. I actually submitted another patch
without long commit message. I will clean up according to your feedback
after getting feedbacks from other people.

The overlap filter needs to cover a full macroblock vertical edge when the
FIELDTX value for two neighbouring macroblocks is not equal. By changing
the internal ordering of the blocks from row major to column major, we do
not need to reinterlace a FIELDTX coded macroblock before running the overlap
The overlap filter is not correct for vertical edges in frame interlaced
I and P pictures. When filtering macroblocks with different FIELDTX values,
we have to match the lines at both sides of the vertical border. In addition,
we have to use the correct rounding values, depending on the line we are
It's in the yuv4mpegenc.c. I added a support for color range by specifying

Make ffmpeg to output stats for each video/audio streams and each ouptut file

as previously all output video/audio sizes were combined to report and it is
unclear such stats is for one output files or aggregates for

Hey,
So this is a problem that has been bugging me for years.
1. The source is udp and the actual source is satellite.
2. Knowing its satellite we also know the stream won't be 100% perfect,
there will be losses.
3. Tranacoding with h264 and fdk-aac and outputting to hls.

Recoding videos with subtitles, I often have problems with subtitle streams,
because the dts starts again with 0 after some time (I think, it is at jumping
from DVD layer 1 to 2, but I'm not sure).
There is code in ffmpeg.c to handle such nonmonolithic dts errors in video and
audio streams, but
