18 mars 2013, par d33pika

The same video plays on Galaxy Beam, Android Version : 2.3.6, stock Video Player. I want to figure out why it does not play on S3. I ran ffprobe and mediainfo on the fie :

I suspect the video player is more stricter on some codec header values. The level is set to 3.0 and this should be correct. Any help in figuring this out is appreciated !

i really want a way i can be able to map every input stream to have an output stream that can be accessed separately from the other like maybe if i need the first stream maybe i will just

ffplay http://localhost:8090/feed1.ffm

and if i need the 7th stream i will just

ffplay http://localhost:8090/feed7.ffm

Please can someone help me crack this issue. FFmpeg dont have complex examples for my current situation.

Concat a video with itself, but in reverse, using ffmpeg

15 février 2017, par Vitam
I was able to reverse with :
```
ffmpeg -i input.mp4 -vf reverse output_reversed.mp4
```
And I can concat with :
```
ffmpeg -i input.mp4 -i input.mp4 -filter_complex "[0:0] [0:1] [1:0] [1:1] concat=n=2:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" output.mp4
```
But can I concat with a reverse version of the video, with a single command ?

What I am trying to achieve is a ping pong effect, where the video plays once, then plays backwards right after.

Thanks !
