MystiQ use ffmpeg to convert. If you known about the arguments to ffmpeg that use your hardware then you can add to MystiQ and use it.

I am aware of that. i just want to convert a mass of wmv and avi files to mp4. and this ffmpeg options are really complicate. i dont have time to spend that much energy in learning all this options. would be great if someone can help me with this.

According to This

I think -hwaccel would do that.

I have a question:According to ffmpeg's documentation page:

Note that most acceleration methods are intended for playback and will not be faster than software decoding on modern CPUs. Additionally, ffmpeg will usually need to copy the decoded frames from the GPU memory into the system memory, resulting in further performance loss. This option is thus mainly useful for testing.

Does this mean that ffmpeg developers advise us not to use hardware acceleration when converting media formats?
