Ajouter notes et légendes aux images

FFmpeg RTSP crash

19 septembre 2016, par bot1131357

I am trying to rtsp stream between two consoles on my computer.

On console 1 I have :

ffmpeg -rtbufsize 100M -re -f dshow -s 320x240 -i video="BisonCam, NB Pro" -r 10 -an -f rtsp -rtsp_transport tcp rtsp://127.0.0.1:8554/demo

On console 2 I have :

ffplay -rtsp_flags listen -i rtsp://127.0.0.1:8554/demo

When I run execute both commands, my webcam LED lights up. But then immediately after ffmpeg crashes. Has anyone encountered the same thing ? I could really use some help here.

This is my ffmpeg configuration on a Windows 10 machine :

Use -h to get full help or, even better, run 'man ffmpeg'

Update

I tried to stream from a video file, just to be sure that the issue is not related to the webcam.

#Console 1

ffmpeg -i out.mp4 -f rtsp -rtsp_transport tcp rtsp://localhost:8888/live.sdp



#Console 2

ffplay -rtsp_flags listen rtsp://localhost:8888/live.sdp?tcp

The output for both consoles are as follows :

Console 1 :

The same crash happened with ffmpeg.exe, and ffplay continued waiting for data. I tried the same commands on a Linux virtual machine, and it worked fine.

Any ideas ?

Update

Update 3

After building my own ffmpeg using the --enable-debug flag, I’m back at it again. Still getting the same error though. Any ideas ? At this point, it seems like there’s something wrong with my computer settings.

ffmpeg command for faster encoding at a decent bitrate with smaller file size

14 septembre 2016, par Blair Holmes

I’m currently using an implementation of ffmpeg on my android app. I’m allowing users to take short videos within my app and then when they upload them to the server, I’m crunching them down with ffmpeg to decrease file size so they’re not passing huge amounts of data over the wire.

the problem is, it’s taking forever to encode the videos on the android device. These videos usually aren’t longer than 45 seconds and can take 20 minutes to encode. I’ve done some playing around with different switches / parameters on the ffmpeg command line and I now have it at a more comfortable time, but the file sizes are significantly bigger. I’m just not sure what codec I should use (fastest encoding but with decent quality output), how ffmpeg handles changing size (aspect ratio) in terms of speed of encoding etc.

Here are the two commands I’ve been using. This first one outputs the file size / quality that I want, but it just takes way too long to encode, not to mention it makes my device get really hot while it’s encoding for so long :

ffmpeg -i input.mp4 -b:v 1024k -c:a copy -vf scale=960:540 output.mp4

I’ve tweaked the bitrate some on that as well as changed the scale to a smaller size, but I don’t want to have to make the videos really small (in terms of scale) to accomplish a faster encoding. this second command goes a lot faster but makes the file size significantly bigger :

ffmpeg -i input.mp4 -vcodec libx264 -preset fast -c:a copy -s 960x540 output.mp4

I’d like to find a happy medium (smaller file size but faster encoding) keeping the video scale size close to the original. ffmpeg just has so many different parameters / switches that it’s difficult to wrap my head around what I should be doing.

EDIT : adding ffmpeg output.

ffmpeg -i input.mp4 -vcodec libx264 -crf 30 -preset veryfast -c:a copy -s 960x540 output.mp4

FFMPEG reconnect input if error

15 septembre 2016, par Alkitab Suhano
I’m finding a way to make ffmpeg reconnect if any error occurered. For my case I restream from hls to rtmp for example
```
ffmpeg -reconnect 1 -reconnect_at_eof 1 -reconnect_streamed 1 -reconnect_delay_max 2000 -i "input" -c:v copy -c:a aac -ar 44100 -ab 128k -ac 2 -strict -2 -f flv rtmp://output
```
FFMpeg always disconnected every 10 minutes. I searched on google and can’t find stable solution for this job.

P.S. OS is linux (Centos 7 64bit)

Thank you,
Akitab
