  I also used SSTV Encoder from F-Droid on Android. It's much more interesting if ran via an analog loop (at least an AUX cable connecting microphone and headphone jacks, or better an external microphone), it gives interesting noise effects. AFAIR, I also experimented with recording it and then playing via https://github.com/bodqhrohro/taporwave https://github.com/bodqhrohro/taporwave, but don't remember if it was decoded well as header tones could be corrupted. I definitely have results of converting raw video to raw audio via ffmpeg and then back, this approach is not sensitive to header pulses (but colour images are borked regardless of the mode). `ffmpeg -y -t 5 -i /downloads/video/webm/414827e0-9583-407f-9940-3840b7b1085f.webm -f rawvideo -s 176x144 /dev/stdout|ffmpeg -y -f u8 -ar 8000 -i /dev/stdin -f ogg /dev/stdout|ffmpeg -y -f ogg -i /dev/stdin -f u8 -ar 8000 /dev/stdout|ffmpeg -y -f rawvideo -s 176x144 -i /dev/stdin /tmp/swine.mp4` : https://0x0.st/HvAM.mp4 https://0x0.st/HvAM.mp4 AUX: https://0x0.st/HvAu.mp4 https://0x0.st/HvAu.mp4 Microphone: https://0x0.st/HvAS.mp4 https://0x0.st/HvAS.mp4 Analog loop (low volume): https://0x0.st/HvAa.mp4 https://0x0.st/HvAa.mp4 Analog loop (overload): https://0x0.st/HvA1.mp4 https://0x0.st/HvA1.mp4 Taporwave: https://0x0.st/HvAj.mp4 https://0x0.st/HvAj.mp4 Don't even remember what: https://0x0.st/HvAQ.mp4 https://0x0.st/HvAQ.mp4 No pigs were harmed during the experiments!
