Hi,

I built the ffmpeg image using the following command line option:

./configure --arch=arm --target-os=linux --enable-cross-compile --cross-prefix=arm-none-linux-gnueabi- --cc=arm-none-linux-gnueabi-gcc --enable-gpl --enable-avfilter --enable-pthreads --enable-postproc --enable-avfilter-lavf --enable-filter=drawtext --enable-static --enable-swscale --enable-debug --disable-shared

I generated the ffmpeg image, but while executing it on Beagle Board i got the following error:

Wht could be the meaning of "could not find codec parameters "…?

Thanks,

does "./ffmpeg -i foreman.yuv out.mpg" work on your PC?

No, after building the FFMPEG binary image, using arm cross-compile toolchain,
i flashed it to my sd card, and while executing it through the board console, using the
command line,

root@beagleboard:/# ./ffmpeg -i foreman.yuv out.mpg

I am encountering the error:

picture size invalid (0x0)

Are any arguments required, or is the command line fine…?

Thanks,

1) before running it on the beagleboard, please go test that 1st on your PC

2) do 1) first

Danke…I will firstly check tht.

Guten Tag,

Hi,

Yep, it worked for the x86 built image, and after tht i tried the same with the ARM
built image on the Board and yeah it worked.
The command should be:

root@beagleboard:/# ./ffmpeg -s 352x288 -ar 128000 -i in.yuv out.mp4

Hence, i gave the input as ‘in.yuv’ raw video and ffmpeg generated the encoded output as
‘out.mp4’.

However, i tried to generate a ‘.264’ encoded output, but i got the following error:

Does FFmpeg support ‘.264’ format ? (“Unable to find a suitable output format for ‘out.264’”)

Danken du und Guten Tag,
