mediafilesegmenter -t 10 -start-segments-with-iframe -f 'output_clear/' bear-1280x720.ts
Produced using Apple's mediafilesegmenter tool also with bear-1280x720.ts as input, but with SAMPLE_AES encryption. (Additional TS packets were constructed manually and prepended to convey the encryption metadata, notably key id and IV).
mediafilesegmenter -S -P -k 'key_iv.bin' -t 10 -start-segments-with-iframe -f 'output/' bear-1280x720.ts
Same as bear-1280x720-hls.ts but with an extra TS packet prepended. This is the same as the first of the metadata packets in bear-1280x720-hls-sample-aes.ts. Its presence indicates that SAMPLE_AES encryption may occur later in the stream, and causes the initial audio and video configs to have an encryption_scheme (of AES-CBC). The actual data is unencrypted, which is indicated by the lack of key ID and IV. This ends up very similar to how clear leader of an otherwise encrypted stream can occur in MP4.

These differ between implementations because color space-converted frames are not specified to the last bit and GLES shader/texture filtering precision varies.

Dumped compressed stream of videos on http://crosvideo.appspot.com manually changing resolutions at random. Those contain 144p, 240p, 360p, 480p, 720p, and 1080p frames. Those frame sizes can be found by
ffprobe -show_frames resolution_change_500frames.vp8
Extract 240 frames using ffmpeg from http://commondatastorage.googleapis.com/chromiumos-test-assets-public/MSE/switch_1080p_720p.mp4.
The frame sizes change between 1080p and 720p every 24 frames.
