FFMPEG .mov to .mp4 convertion failure [solved]
24 mai 2016, par Pasha RumkinI’m converting .mov and .mp4 to .mp4 with FFMPEG to play them on iOS and Android devices. Mp4 from Android is converting properly and playing on both devices iPhone and Android. But iPhone’s .mov result is strange. It’s playing on iPhone and Android 4. But when I’m trying to open this video with Photo app (Android 5, 6) it outputs unsupported video message.
FFMPEG command :
ffmpeg -i app/data/storage/68/fa/39/68fa392b-df25-4622-93ab-cf9bf1253f63 \

Can I record a video without using UIImagePickerController ?
24 mai 2016, par SUKIYAKICan I record a video without using UIImagePickerController ?
Of course without needing to jailbreak or anything else that would cause the App Store to reject the app.I think there is a way to access video device not using UIImagePickerController because these camera applications can record video and work on iPhone 2G/3G which utilizes ffmpeg :
I pick this code up by googling.
AVFormatParameters formatParams;
AVInputFormat *iformat;
formatParams.device = "/dev/video0";
formatParams.channel = 0;
formatParams.standard = "ntsc";
formatParams.width = 640;
formatParams.height = 480;
formatParams.frame_rate = 29;
formatParams.frame_rate_base = 1;
filename = "";
iformat = av_find_input_format("video4linux");
av_open_input_file(&ffmpegFormatContext,
filename, iformat, 0, &formatParams);This code tell me how to open camera device, but I don’t know device path of iPhone.
How do iVideoCamera and iVidCam record video ?
