[Solved]Post processing with ffmpeg for roku direct play

[philhachey]

I'm trying to get this post script working in lubuntu

### Transcode mp4 files for the roku

if [ -z $1 ]; then
echo "Usage: `basename $0` filename"
exit 0
fi

Wait while any other ffmpeg processes are running
while [ -n "$(ps -ef | egrep "ffmpeg" | grep -v grep)" ];
do
echo -e "\n[$(date +%b\ %d\ %Y:\ %H:%M:%S)]\nFound another instance of ffmpeg running, pausing 5 minutes..."
sleep 300
done

# ffmpeg cmd
ffmpeg -y -i $1 -mbd rd -trellis 2 -cmp 2 -subcmp 2 -g 100 -pass 1 -acodec libfaac -ab 192k -ac 2 -threads 0 $1.mp4

exit 0

For some reason it keeps giving the error: "ffmpeg: command not found"

I have ffmpeg built from source with h246 and the command was copied (after running and working) directly from a terminal.

Any help would be appreciated.

Ok, new problem.

Here is the script and how it has been modified so far

#!/bin/bash

### Transcode mp4 files for the roku

if [ -z $3 ]; then
echo "Usage: `basename $0` filename"
exit 0
fi

#Wait while any other ffmpeg processes are running
while [ -n "$(ps -ef | egrep "ffmpeg" | grep -v grep)" ];
do
echo -e "\n[$(date +%b\ %d\ %Y:\ %H:%M:%S)]\nFound another instance of ffmpeg running, pausing 5 minutes..."
sleep 300
done

# ffmpeg cmd
/home/phil/ffmpeg/ffmpeg -i /media/Media/tv/$3.* -mbd rd -trellis 2 -cmp 2 -subcmp 2 -g 100 -pass 1 -acodec libfaac -ab 192k -ac 2 -threads 0 /media/Media/tv/$3.mp4

exit 0

As you can see I just needed to point to the installation path of ffmpeg as well as the full file input and output paths and change the $1(folder) to a $3(clean job name).*

So the problem now is it starts up ffmpeg but closes with this:

I am trying to work through this on my own the best I can but would appreciate any help.

Stream #0:1: Audio: none, 48000 Hz, stereo, s16, 128 kb/s

That seems like it cannot find the libfaac codec, or some other issue with the uadio related parameters.

[philhachey]

I just tried it with the perameters: -acodec copy and -vcodec copy. separately.

the audio codec worked but the video codec gave me the same error.

[philhachey]

Since the command works in terminal I have compared the outputs line for line:

"ratecontrol_init: can't open stats file"

Is where it seems to be going wrong.

Now I'm wondering if this is a permissions issue or maybe it cant find the stats file???

I guess the real question is why does it work in terminal but not as a post script?

[philhachey]

Got it!

The problem was with the "-pass 1" command.
