MPEG2 Transport Stream is a Audio/Video container format used to encapsulate a multimedia stream containing audio, video and other metadata. It is the commonly used Broadcast format.

MPEG transport stream (MPEG-TS, MTS or TS) is a standard format for transmission and storage of audio, video, and Program and System Information Protocol (PSIP) data. It is used in broadcast systems such as DVB, ATSC and IPTV.

Transport Stream is specified in MPEG-2 Part 1, Systems (formally known as ISO/IEC standard 13818-1 or ITU-T Rec. H.222.0).

Transport stream specifies a container format encapsulating packetized elementary streams, with error correction and stream synchronization features for maintaining transmission integrity when the signal is degraded.

Transport streams differ from the similarly named program streams in several important ways: program streams are designed for reasonably reliable media, such as discs (like DVDs), while transport streams designed for less reliable transmission, namely terrestrial or satellite broadcast. Further, a transport stream may carry multiple programs.

detect key-frame in TS with H264 codec

Is there an easy not horrifyingly complex way to detect key-frame in an H264 video stream wrapped in a Transport Stream? Also, if extra previous packets needed for the decoding of the key-frame is there a way to find those as well?

H.265/HEVC support for HLS in iOS 9?

Currently, HLS (HTTP Live Streaming) requires the content to be video H.264 and/or AAC/MP3/sound. Is there support for H.265/HEVC for HLS in iOS 9? If not, is there any way to bypass this limitation and use TS files that are H.265 encoded?
