Sorry for the noise–I didn't expect that to actually appear on the ML. I
was attempting to test the "Your message to ffmpeg-user awaits moderator

ffprobe can be used to get width and height for the showwaves size
option.

Your ffmpeg isn't compiled with libmp3lame or any other mp3 encoder,
please replace "mp3" with "aac" for this test.

showwaves is an audio filter, it has no access to the dimensions of the
video, unfortunately.

Since its output is video though, you could in theory make it very
large and then scale it down, but there's also no way for one video's
filters (such as "scale") to know another video's dimensions. :(

You need to use Parsed_drawtext_X instead of drawtext, replace X with
number of filter in filtergraph.

So if its 3rd filter in filtergraph its number will be 2. Because
lavfi counts from 0.

[FFmpeg-user] RES: Memory usage growing when using ffmpeg. Is this expected?

[Guilherme de Oliveira Costa]

Reindl,

The issue is that the system was dedicated to recording the video. Usually the 
memory consumption baseline is around 8MB. Once there are other applications 
running, such a memory usage is troublesome.

As I said, this is an _embedded_ system. I was presented with these restraints, 
and I need to evaluate if it is possible to record videos within such 
restraints.

very high is relative

and it did not abort with a out-of-memory on a 64 MB device and so finished - 
what to complain then - memory is there to be used and 64 MB in 2017 i would 
not expect to run anything which does really some work

there are even not much systems booting with 64 MB todays when every clock has 
1 GB or more

if there would be memory leaks you would end with OOM very large on such a

[FFmpeg-user] sendcmd and drawtext - using more than one in the same filtergraph?

[Mark Burton]

Using a single sendcmd to read text from an external file and command a single 
drawtext, is working fine:

ffmpeg -i input.mov -c:v dnxhd -b:v 115M -pix_fmt yuv422p -vf 
"sendcmd=filename=commandFile1,drawtext=fontfile=/System/Library/Fonts/Helvetica.dfont:fontsize=20:fontcolor=white:x=10:y=30:text="
 -an output.mov

However I need to have two or more drawtext filters being commanded from 
separate sendcmd files in the same filtergraph.

I believe I need to assign filter instance names to each drawtext command and 
then reference that name for [TARGET] in the sendcmd text file, but after 
reading through the docs and trying a few ideas, I’m no closer.

The basic command (currently not working):

ffmpeg -i input.mov -c:v dnxhd -b:v 115M -pix_fmt yuv422p -vf 
"sendcmd=filename=commandFile1,drawtext=fontfile=/System/Library/Fonts/Helvetica.dfont:fontsize=20:fontcolor=white:x=10:y=30:text=,sendcmd=filename=commandFile2,drawtext=fontfile=/System/Library/Fonts/Helvetica.dfont:fontsize=20:fontcolor=red:x=10:y=60:text="
 -an output.mov

Result:
drawtext 1 - after 1 frame at each new text entry, text from commandFile2 is 
overriding text from commandFile1.
drawtext 2 - nothing is being drawn by this filter.

...contents of the sendcmd files:

commandFile1
00:00:00.000-00:00:01.000 [enter] drawtext reinit 'text=Note A';
00:00:01.000-00:00:01.958 [enter] drawtext reinit 'text=Note B';

commandFile2
00:00:00.000-00:00:01.000 [enter] drawtext reinit 'text=Tag 1';
00:00:01.000-00:00:01.958 [enter] drawtext reinit 'text=Tag 2';

… and the output:

very high is relative


For example, I use an embedded device with 64 MB of RAM, and when I recorded a 
30 minute video, I was left with 2MB of RAM in the last minutes of the 
recording.


and it did not abort with a out-of-memory on a 64 MB device and so 
finished - what to complain then - memory is there to be used and 64 MB 
in 2017 i would not expect to run anything which does really some work


there are even not much systems booting with 64 MB todays when every 
clock has 1 GB or more



I used valgrind to check for memory leaks, but I only found a 24 byte leak when 
the program finishes. Is this memory consumption expected for ffmpeg?


if there would be memory leaks you would end with OOM very large on such 
a device

Re: [FFmpeg-user] Problem with ffmpeg command when recording live streams

[DopeLabs]

Have you tried a stream copy or only encoding the audio to mp3/aac since the 
video looks like its already in h264?

Stream copy video and re-encode audio

ffmpeg -I rtsp:/ip -c:v copy -c:a mp3 -b:a 128k -movflags +faststart -f mp4 
outfile.mp4

[FFmpeg-user] Memory usage growing when using ffmpeg. Is this expected?

[Guilherme de Oliveira Costa]

Hi,



I am using ffmpeg record a video from a webcam, but the memory usage is very 
high, and keeps increasing with video length.

For example, I use an embedded device with 64 MB of RAM, and when I recorded a 
30 minute video, I was left with 2MB of RAM in the last minutes of the 
recording.

I used valgrind to check for memory leaks, but I only found a 24 byte leak when 
the program finishes. Is this memory consumption expected for ffmpeg?

This is the ffmpeg command I used:

ffmpeg -f video4linux2 -s 320x240 -t 00:00:10 -i /dev/video0 out.mpg

[FFmpeg-user] Dimensions of the input video as a variable

[Wolfgang Hugemann]

I would like to superimpose the audiograph of the video's audio on the 
video itself using 'blend'. I sucseeded in doing so with the line:


c:\programme\ffmpeg\bin\ffmpeg -y -i test.avi -filter_complex 
"[0:a]showwaves=s=640x480:mode=line[waves];[0:v]setsar=1:1[video];[waves][video]blend=all_mode='lighten'" 
-c:v libxvid -c:a copy ovl.avi


As you see, I supplied the dimensions of the input video (640x480) in 
the command line. I would like to turn this into a more general script, 
determining the dimensions of the input video on the fly, but how do I 
do that?


I tried "s=wxh" and alike, by that doesn't seem to work.

Wolfgang

​From that, I'd say the input file is damaged and ffmpeg can't get the
video parameters, especially the actual layout and resolution of the video
stream.

Does the file play fine with ffplay or other players? Usually ffmpeg does a
good job of recovering some damages, but it vary from codec to codec.​

Dear Cley,

here it is

ffmpeg -i HYPERS.MOV -c:v copy -an output.avi

HYPERS.MOV is a mov quicktime with a xvid video stream and no sound
the stream ha no keyframe - it is normal, so i do not want to re encode it.
