I have VLC but I need to be able to use iOS apps to play these videos, but QuickTime barfs on them. They seem to play okay if I media serve them out to the iOS device, but I do need to get them to play on QuickTime. The original videos are MPEG-H Part 2/HEVC (H265). Here is the output of ffprobe <video.mp4> -hide_banner: Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Video1.mp4': Metadata: major_brand : mp42 minor_version : 0 compatible_brands: mp42mp41 creation_time : 2021-10-24T23:18:14.000000Z Duration: 00:07:24.31, start: 0.000000, bitrate: 16553 kb/s Stream #0:0(eng): Video: hevc (Main) (hvc1 / 0x31637668), yuvj420p(pc, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 16357 kb/s, 60 fps, 60 tbr, 60k tbn, 60 tbc (default) Metadata: creation_time : 2021-10-24T23:18:14.000000Z handler_name : ?Mainconcept Video Media Handler encoder : HEVC Coding Stream #0:1(eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 189 kb/s (default) Metadata: creation_time : 2021-10-24T23:18:14.000000Z handler_name : #Mainconcept MP4 Sound Media Handler QT simply gives up and says it cannot play this video. VLC has no problems. I attempted to convert to H.264, thinking that might be the issue using the ffmpeg command: ffmpeg -i Video1.mp4 -bsf:v h264_mp4toannexb -sn -map 0:0 -map 0:1 -vcodec libx264 Video1.ts However, QuickTime, again, barfs while VLC works just fine. When I look at the covered file using ffprobe I see - Input #0, mpegts, from 'Video1.ts': Duration: 00:07:24.28, start: 1.423311, bitrate: 6129 kb/s Program 1 Metadata: service_name : Service01 service_provider: FFmpeg Stream #0:0[0x100]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuvj420p(pc, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 60 fps, 60 tbr, 90k tbn, 120 tbc Stream #0:1[0x101](eng): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, fltp, 384 kb/s So I am unsure what needs to happen to get QuickTime to grok it (QuickTime is not saying why it won't open). Is it the audio? converting form aac to mp2? ________________________________ Keep using H264 but make sure that the audio codec is AAC and the wrapper is MP4 not MPEGTS
Sorry, just to be clear when you say 'not MPEGTS' I should save it as Video1-converted.mp4, not Video1.ts?
I will RTFM to find the commands to preserve the AAC codec. I just assumed that since the original was AAC then the converted would use it as well.
