Hello, Could you share a URI for one of these videos? Also, do they play on mobile before you add the text filter?

I have noticed that some of my videos, encoded with ffmpeg and uploaded to my websites, do not play on mobile web browsers, but they work perfectly well on desktop browsers on my Linux machine. I get either a message saying 'file is corrupted' or no message at all (just a blank video) depending on the browser. I've tried Brave, Firefox and Chrome, on an iPhone, a Samsung tablet and a Samsung Galaxy s10 plus. The 'bad' videos consistently fail to play on mobile devices. I've run an ffprobe on two .mp4 files: one which works on a mobile and desktop browser (good.mp4) and one which will only play on a desktop browser (bad.mp4. These are partial outputs (the rest of the output for the two files seems identical): Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'bad.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf58.76.100 Duration: 00:00:30.02, start: 0.000000, bitrate: 1582 kb/s Stream #0:0(und): Video: h264 (High 4:2:2) (avc1 / 0x31637661), yuv422p10le(tv, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 1574 kb/s, 24 fps, 24 tbr, 12288 tbn, 48 tbc (default) Metadata: handler_name : VideoHandler vendor_id : [0][0][0][0] Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 2 kb/s (default) Metadata: handler_name : SoundHandler vendor_id : [0][0][0][0] Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'good.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf58.76.100 Duration: 00:00:30.00, start: 0.000000, bitrate: 4824 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt470bg/unknown/unknown), 1920x1080 [SAR 1:1 DAR 16:9], 4821 kb/s, 24 fps, 24 tbr, 12288 tbn, 48 tbc (default) Metadata: handler_name : VideoHandler vendor_id : [0][0][0][0] The command I used to encode them both (via a bash scrip on Linux) is for f in *.mp4 do ffmpeg -i "$f" -vf "drawtext=text='© Mark A.
