Other interesting software

Override matched Line
2 février 2016, par jb_alvaradoWhen I print the output from ffmpeg to a file, I get something like this :
[...]
frame= 28 fps=0.0 q=-0.0 size=N/A time=00:00:01.16 bitrate=N/A speed=2.31x
frame= 55 fps= 54 q=-0.0 size=N/A time=00:00:02.24 bitrate=N/A speed= 2.2x
frame= 84 fps= 55 q=-0.0 size=N/A time=00:00:03.40 bitrate=N/A speed=2.22x
frame= 112 fps= 54 q=-0.0 size=N/A time=00:00:04.52 bitrate=N/A speed=2.17x
[...]Now I would like that all lines that matches with
frame=*
get replaced and only the last current line get printed to the text file (in real time).Is this possible ?
At the moment I have this line :
ffmpeg -v info -i input.ext -f null 2>&1 | awk '/frame=/{gsub(/.*/, $0)};{print}'
It works almost, except that all line with contain
frame=*
are empty. -
avcodec/jpeglsenc : Only use one line at a time as spare buffer
3 septembre 2020, par Andreas Rheinhardtavcodec/jpeglsenc : Only use one line at a time as spare buffer
ls_encode_line() encodes one line of input from left to right and
to do so it uses the values of the left, upper left, upper and upper
right pixels for prediction (i.e. the values that a decoder gets when it
decodes the already encoded part of the picture). So a simple algorithm
would use a buffer that can hold two lines, namely the current line as
well as the last line and swap the pointers to the two lines after
decoding each line. Yet if one is currently encoding the pixel with
index k of a line, one doesn't need any pixel with index < k - 1 of the
last line at all and similarly, no pixels with index >= k have been
written yet. So the overlap in the effective lifetime is pretty limited
and since the last patch (which stopped reading the upper left pixel and
instead reused the value of the upper pixel from the last iteration of
the loop) it is inexistent. Ergo one only needs one line and doesn't
need to swap the lines out.Signed-off-by : Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

Extract H.264 data for a P-Frame using command line
10 décembre 2019, par cloudravenI want to use ffmpeg to extract frame data from command line, similar to what av_read_frame does. I want to extract the full data of arbitrary frames without decoding or re-encoding them. (i.e. I expect extracted P-frames to be very small and not reconstructed from their reference frames)
I know I can code a tiny tool for doing this, but I suspect this functionality may be already exposed through a bitstream filter in the command line. Is that the case ?
