Comment(by tralph11@…):
This video was broken by changeset [22427] which uses the h264_parser to
determine if we are on_frame. It appears the provided video has somewhat
periodic packets that the h264 parser doesn't understand. I'm guessing
these packets are the keyframes. The proper fix is to update the h264
parser to correctly identify these packets. For the time being I'm
providing a patch that will increment framesRead when the packet is not
identified. I also have extracted the first packet which is not properly
identified. Someone who knows much more about h264 decoding will need to
look at this.
