I used the following command to get the frames from RTSP h264 codec. I could not able to get the frames from the ip camera.
$ ffmpeg -i rtsp://xxxx:yyy#192.168.1.yy:xx/tcp/av0_0 -f image2 -vf fps=fps=1/120 img%03d.jpg

I am using the following command on several video streams to pipe them into my TVHeadend server.
pipe:///usr/bin/ffmpeg -i *URL* -c copy -metadata service_provider="My Provider" -metadata service_name="My Service"-f mpegts pipe:1
This command works fine for most of the streams, but a few are throwing this error...

The problem streams do work.
I searched before asking this question and everything I found was related to conversion.
Can anyone see what I am doing wrong?
The reason behind the using FFmpeg and piping is to eliminate issues with stream freezes. FFmpeg just handles hitches etc better than simply adding the URL straight into my TVHeadend server.

The video size 480x640 is correct, but it only lasts 2 seconds, only contains the first image 1.jpg, please tell me how I can solve this problem?

So I'm working with a video build out of pngs. Making a video hasn't been too hard thanks to ffmpeg however most of the videos I've made work great playing forward and are extremely choppy playing backwards.
Using a program named MPEG Streamclip plus Handbrake I managed to convert my video to one that plays great forward and backward. But now I can't figure out how to pass in the right options to ffmpeg to replicate this video.
Using ffprobe I have some outputs of the good and bad video. What options am I missing?
Bad Video:

FFMPEG Command so far:
ffmpeg -y -i 'pngs/tea-%03d.png' -vf scale=674:-2 -vcodec libx264 -pix_fmt yuv420p -r 25 tea_ffmpeg.mov
I understand mov vs mp4 should just be a container spec, but mov was the first I got working. I'm more than happy to use mp4.
The main thing that stands out is the profile. So,
ffmpeg -y -i 'pngs/tea-%03d.png' -vf scale=674:-2 -vcodec libx264 -profile:v main -pix_fmt yuv420p -r 25 tea_ffmpeg.mov
To be safer, you can use baseline profile and small GOP sizes (at some cost to file size)
ffmpeg -y -i 'pngs/tea-%03d.png' -vf scale=674:-2 -vcodec libx264 -profile:v baseline -g 12 -pix_fmt yuv420p -r 25 tea_ffmpeg.mov
I have some .mp3 audio files, with different "configuration" like sample rate, bit rate, etc.
For my app, one of them is working and the rest, not.
How can I convert the rest of them using the working file's "configuration"?

You probably need to change the channel layout and/or sample rate:
ffmpeg -i input.mp3 -c:a libmp3lame -ar 22050 -ac 1 output.mp3
Try 3 commands: one without -ar 22050, one without -ac 1, and one with both as shown above.
I am trying to add watermark with transparent background on OSX with ffmpeg.

I thought I am missing png support and I checked homebrew for libpng install, but it turn out png support is already included by Apple with OSX.
Also I did
ffmpeg -codecs list | grep -i png
and I do have PNG support in ffmpeg:
DEV D png PNG (Portable Network Graphics) image
Is yor file 16bit grayscale with alpha? It looks like ffmpeg doesn't support this combination. Try converting it to 8bits and/or RGBA.
