Invalid argument supplied on line 371.

I'm getting the same with PHP 5.2.

Looks like it is an issue with this set of code:

    $output = ffmpeg_wrapper_run_command('-formats');

    // parse the list
    // we know where the codecs are by looking at the output of ffmpeg -formats
    $codecs_formats_pos = strpos($output, "Codecs:");
    $codecs_formats_pos_end = strpos($output, "Supported file protocols:");
    $codecs = substr($output, $codecs_formats_pos, ($codecs_formats_pos_end - $codecs_formats_pos));

    // remove the extra text
    $codecs = str_replace('Codecs:', '', $codecs);
    // convert to array
    $codecs = explode("\n", $codecs);

The substr is returning an empty string, which results in an empty array for the subsequent foreach (a few lines down). Ultimately, this then returns an empty array to line 371.

Can you confirm this under the 6.2.x branch?

Looks like the command to ffmpeg has changed parameters. It should be "-codecs" vs. "-formats". Patch is attached.

Steps to Resolve:

1. Upload Patch [formatspatch.patch] to ffmpeg_wrapper
2. Apply Patch (within ffmpeg_wrapper directory)
patch < formatspatch.patch
3. Clear Cache (command below for drush-enabled sites)
drush cache-clear all
4. Test

No, I'm using 6.x-1.1-beta2

Can you try the 6.2.x branch and confirm this? If you look at class_ffmpeg_wrapper, get_codecs() this change should be correctly accounted for.

Sorry, seems like we keep overlapping one another in posts here.

In the dev version of 6.1.x this should be correctly handled. ffmpeg_wrapper_get_codecs() checks for the version before trying to do formats or codecs. If you could testwith the 6.2.x branch though- that's where all future work will go- that'd be awesome as I would like to drop the 6.1.x as soon as possible.

Based on inspecting the CVS, it looks to be appropriately handled in 6.2.x (much more elegantly than the patch does, I might add). I'll test and report back.

How close/stable is -dev? I really need this module for a site going to production by end of year and that was the reason for choosing the alpha over dev. Does the 6.2.x branch have an alpha/beta/official release in the works?

The 6.2.x should be no more/less stable than the 6.1.x. The main difference is in some of the UI functionality which allows for testing transcoding of files. In terms of their architectural differences, 6.2.x is redone, but basically using the same functions from 6.1.x. I think they are pretty much compatible.

@ayalsule

Did you clear cache, etc? What is the file format you're converting from and to? Does the ffmpeg install (not the drupal module) handle it? Are you using default settings? I was able to successfully move several video files (mainly avi) to flv without issue. As arthurf noted, 2.x dev may be a better alternative - or 1.x dev.

@arthurf

I tested 6.2.x dev without success. The AJAX call is failing on the conversion - still investigating why.

Thanks for the help and info.
