I have installed avserver (Libav) earlier to ffmpeg.Kindly suggest any alternative to live=1 or provide suggstion.
This works for ffmpeg version N-71741-ge2877bd :
ffmpeg -rtmp_live live -i "rtmp://IP/live/1234" -f flv rtmp://IP/live/1234_56

How can I merge two .g729 files into one .wav file with ffmpeg?
I used the command
ffmpeg -filter_complex [0\:a][1\:a]amerge\=inputs\=2[aout] -map [aout]
The result is with two files reported .wav and not .g729 and output reported .wav
Here is the FFMPEG data:

With ffmpeg 3.4, you can now render svg image sequences. With the following it works:
ffmpeg -i images/image-%02d.svg video.mp4
However, piping via
cat images/*.svg | ffmpeg -f image2pipe -c:v svg -i - video.mp4
results in the following error

const uint8_t *end = p->buf + p->buf_size;
if (memcmp(p->buf, "<?xml", 5))
return 0;
while (b < end) {
b += ff_subtitles_next_line(b);
if (b >= end - 4)
return 0;
if (!memcmp(b, "<svg", 4))
return AVPROBE_SCORE_EXTENSION + 1;
}
return 0;
}
All of the svg files in the folder have the appropriate headers
<?xml version="1.0" encoding="utf-8"?>
<svg xmlns="http://www.w3.org/2000/svg" width="640" height="640">
What am I missing?
Lastly, I'm using a compiled version of ffmpeg since installing via brew install ffmpeg --with-librsvg didn't seem to work. It installed fine, however it would give the following error
Decoder (codec svg) not found for input stream #0:0
Every time I run this script it doesn't work. I get the output bash: command not found
I ran bash -x to see what was the problem but I don't understand the errors

The solution is of course in the comment by codeforester:
#!/bin/bash
for file in *.mp3; do
ffmpeg -i "$file" -acodec pcm_s16le -ac 1 -ar 44100 "${file%.mp3}".wav
done
(added 44100 per comment LordNeckbeard)
Some hints:
1) if you split your script over multiple lines, it becomes easier to spot errors like this.
2) Don't focus too much on the errors when running bash -x; it gives the on the output the commands. That what it is for. In this case:
+ ffmpeg -i '' -acodec pcm_s16le -ac 1 -ar .wav
The conclusion from this line is that ffmpeg is run with '' as input file and .wav as output.
I have two cameras: an Axis P1347 and an Axis P1357. ffmpeg gets a 400 Bad Request on the P1347 but everything works fine with the P1357.
I am able to successfully stream rtsp video using vlc from an Axis P1347 Camera using the following url:
rtsp://10.8.3.85:554/axis-media/media.amp?videocodec=h264&audio=1
However, this same url in ffmpeg gives the following for the Axis P1347 Camera:

Obviously rtsp is turned on and working if vlc can display video, correct? So why does VLC work with the camera, but not ffmpeg? Note ffmpeg is installed and works correctly with a similar camera.
It turns out the P1347 is outputting a 64 bit codec which ffmpeg does not have codecs to ingest. VLC had the 64 bit codecs installed.
I will research how to install 64 bit codecs and use them for the P1347 camera.
I am trying to encode my video using ffmpeg. I have taken output of each frame as a separate image and then I'm joining them into a video using ffmpeg. I compiled ffmpeg from source.
This is the command I used and the errors I keep running into!
