Okay, I played a bit around with the atrim Filter, but the manual isn't very
helpful here. I've tried the following:
C:\ffmpeg -i test.mxf -vcodec copy -map 0:v -acodec pcm_s24le -map 0:1 -map
0:2 -filter_complex [a:1]atrim=start=0.035 test_new.mxf

Hi Alex,
I guess there is somehing wrong with the channel mapping, but without the
fliter_complex the mapping seems to be okay.
I think the filter_complex messes up the mapping. Note this mapping
from your output:
Stream mapping:
Stream #0:2 (pcm_s24le) - atrim
atrim - Stream #0:0
I observed that start times and durations changed when transcoding
whatever input (tried a few) to wmv/wma in a wmv container.
Here's a sample command line with output:
ffmpeg -f lavfi -i testsrc=s=640x480:d=1 -f lavfi -i
sine=frequency=1000:sample_rate=48000:duration=1 -c:v wmv2 -c:a wmav2
Dear All,
Just joined the mailing list.
Looking for a video player in a browser, that will play:
mp4 video codec, aac audio codec, and floor audio, en, fr, ger, tr translations.
Each audio channel will be selected in the browser in most platforms.
I have managed to:
ffmpeg -i 00.mp4 -i 01.mp4 -i

Hi there.
I have begun playing around with using a wearable camera that just clips
into your shirt, like w mic clip.
It records MJPEG at 720x480 which is enough for my uses, recording daily
walks around the city.
But there's one issue I had not taken into account: the body (actually
torso) where

those are better.
I think I have read something, but can't recall where.
That said, have you looked at
