In most of case, `ffmpeg` autodetect all needed options to read a video/audio stream or file. But it is possible in rare cases that's needed to set a option to help `ffmpeg`. Per default `ffmpeg` use 5 seconds to detect all options or abort. In most cases, `ffmpeg` automatically detects all needed options to read a video or audio stream or file. But it is possible in rare cases that you will need to set options to help `ffmpeg` out.

Now you can see what going wrong. Following list could be help to solve your trouble: Now you should be able to see what is going wrong. The following list contains some common problems and solutions:
- `[rtsp @ ...] UDP timeout, retrying with TCP`: You need to set RTSP transport in the configuration with: `input: -rtsp_transport tcp -i INPUT` - `[rtsp @ ...] UDP timeout, retrying with TCP`: You need to set an RTSP transport in the configuration with: `input: -rtsp_transport tcp -i INPUT`
- `[rtsp @ ...] Could not find codec parameters for stream 0 (Video: ..., none): unspecified size`: FFmpeg need more data or time for autodetect. You can set the `analyzeduration` and/or `probesize` option, play with this value. If you know the needed value you can set it with: `input: -analyzeduration xy -probesize xy -i INPUT`. More information about that can be found on [FFmpeg](https://www.ffmpeg.org/ffmpeg-formats.html#Description). - `[rtsp @ ...] Could not find codec parameters for stream 0 (Video: ..., none): unspecified size`: FFmpeg needs more data or time for autodetection (the default is 5 seconds). You can set the `analyzeduration` and/or `probesize` options to experiment with giving FFmpeg more leeway. If you find the needed value, you can set it with: `input: -analyzeduration xy -probesize xy -i INPUT`.
