file exist but 'no such file or directory'
Robot Ijo
i try to publish video stream using my android with ffmpeg.
The file that i want to publish is sample.mp4 in /sdcard/tobor
directory.
sample.mp4 is existed, but ffmpeg complained that sample.mp4 not exist.
Any idea ? maybe i missed some basic principle on android.
These are list of commands:
# ls
sample.mp4
ffa_s
# ffmpeg -i sample.mp4

Do you mean this
http://developer.android.com/reference/android/Manifest.permission.html#WRITE_EXTERNAL_STORAGE
I don't use manifest file, i copied the file directly with 'adb push'.
I have write access to /sdcard and /system.
Thanks,
elik
ffmpeg converts files from one format/codec to another it doesn't
publish anything as far as I know.
You need an output file for the ffmpeg command e.g:
ffmpeg -i sample.mp4 sample.mov

Sorry, this is the complete command:
# ffmpeg -i sample.mp4 -re -acodec copy -vcodec copy -f flv
rtmp://mydomain.com/live/myStream
But, it will produce some error message.

We can publish video stream using ffmpeg to some server like wowza or
redis.

I can read another file with same permission (wek.txt).
Btw, why the owner of these files is not 'root' ?

Just want to know :).Because this is what happen in linux. When 'root'

I have a similar problem as mentioned in this discussion.
I am trying to run following command in android emulator:
ffmpeg -i /data/sample_music.wma /data/out_music.mp3
and the output is as follows:
