Please, fix coding style issues before landing.

> Source/WebCore/platform/graphics/gstreamer/WebKitWebSourceGStreamer.cpp:1019
> +    // priv->size == 0 if received length on didReceiveResponse < 0

Nit: According to the coding style comments should finish with a period.

> Source/WebCore/platform/graphics/gstreamer/WebKitWebSourceGStreamer.cpp:1020
> +    if (priv->size != 0 && priv->offset > priv->size) {

This is confusing offset and size are both unsigned so if offset == 0 it will never be > size. This could probably just be 

if (priv->offset > priv->size)

> Source/WebCore/platform/graphics/gstreamer/WebKitWebSourceGStreamer.cpp:1021
> +        GST_DEBUG_OBJECT(m_src, "Updating internal size from %ld to %ld", priv->size, priv->offset);

size and offset are guint64, you should probably use G_GUINT64_FORMAT instead of %ld.

Done

But IIRC, if priv->size == 0 (set in didReceiveResponse) we don't want/need to update the internal size as didReceiveResponse will disable seek, etc on the gst appsrc. No change here

You are right, I read the comparison wrongly. But still, you should do:

if (priv->size && priv->offset > priv->size)

or 

if (priv->size > 0 && priv->offset > priv->size)

to make the style bot happy.
