A 960x540 H.264 mp4 video with 4 color blocks (Y,R,G,B) in every frame. The video playback looks like a still image. An image of 4 color blocks (.png file) is first created by Windows Paint.exe. This image is then used as a basic video frame in making this 2-second video from Mac iStopMotion.

four-colors-aspect-4x3.mp4

Actual video frames are the same as four-colors.mp4, except it specifies an aspect of 4x3 in mp4 meta data.

MSE MP4 keyframe-metadata versus encoded AVC keyframe-ness test media

bear-640x360-v-2frames_frag.mp4

Just first 2 video frames of bear-640x360-v_frag.mp4, created with:

ffmpeg -i bear-640x360-v_frag.mp4 -vcodec copy -movflags frag_keyframe+empty_moov+default_base_moof \
    -vframes 2 bear-640x360-v-2frames_frag.mp4

It‘s 1 keyframe + 1 non-keyframe, with container’s frame keyframe-ness correct.

bear-640x360-v-2frames-keyframe-is-non-sync-sample_frag.mp4

This is bear-640x360-v-2frames_frag.mp4, with manually updated trun.first_sample_flags: s/0x02000000/0x01010000 (first frame is non-sync-sample, depends on another frame, mismatches compressed h264 first frame's keyframe-ness).

bear-640x360-v-2frames-nonkeyframe-is-sync-sample_frag.mp4

This is bear-640x360-v-2frames_frag.mp4, with manually updated tfhd.default_sample_flags: s/0x01010000/0x02000000 (second frame is sync-sample, doesn‘t depend on other frames, mismatches compressed h264 second frame’s nonkeyframe-ness).

HLS

bear-1280x720-hls.ts

Produced using Apple's mediafilesegmenter tool with bear-1280x720.ts as input, with no encryption.

mediafilesegmenter -t 10 -start-segments-with-iframe -f 'output_clear/' bear-1280x720.ts

bear-1280x720-hls-sample-aes.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

bear-1280x720-hls-with-CAT.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.
