• playback of ffmpeg converted video on LDPI device (Samsung S5300 240 x 320)

  25 décembre 2013, par user737486

  I have Full HD video taken by Samsung Galaxy S4 camera.
  video stream info as follows :

  {"index":0,"codec_name":"h264","codec_long_name":"H.264 \/ AVC \/ MPEG-4 AVC \/ MPEG-4 part 10","profile":"High","codec_type":"video","codec_time_base":"1\/180000","codec_tag_string":"avc1","codec_tag":"0x31637661","width":1920,"height":1080,"has_b_frames":0,"sample_aspect_ratio":"0:1","display_aspect_ratio":"0:1","pix_fmt":"yuv420p","level":40,"r_frame_rate":"30\/1","avg_frame_rate":"21240000\/707831","time_base":"1\/90000","start_pts":0,"start_time":"0.000000","duration_ts":1415662,"duration":"15.729578","bit_rate":"16553536","nb_frames":"472","disposition":{"default":1,"dub":0,"original":0,"comment":0,"lyrics":0,"karaoke":0,"forced":0,"hearing_impaired":0,"visual_impaired":0,"clean_effects":0,"attached_pic":0},"tags":{"rotate":"90","creation_time":"2013-12-24 10:19:18","language":"eng","handler_name":"VideoHandle"}}

  in short it is 1920x1080, 16KK bitrate, rotation : 90.
  I'm converting it using ffmpeg by the following command :

  ffmpeg -y -threads 8 -i input.mp4 -vcodec libx264 -vpre ipod640 -s 324x576 -strict -2 -b:v 512k -acodec aac -ac 1 -ar 16000 -ab 32000 -vf "transpose=1" -metadata:s:v:0 rotate=0  output.mp4

  The output video stream info :

   {"index":0,"codec_name":"h264","codec_long_name":"H.264 \/ AVC \/ MPEG-4 AVC \/ MPEG-4 part 10","profile":"Constrained Baseline","codec_type":"video","codec_time_base":"1\/48","codec_tag_string":"avc1","codec_tag":"0x31637661","width":324,"height":576,"has_b_frames":0,"sample_aspect_ratio":"0:1","display_aspect_ratio":"0:1","pix_fmt":"yuv420p","level":30,"r_frame_rate":"24\/1","avg_frame_rate":"24\/1","time_base":"1\/12288","start_pts":0,"start_time":"0.000000","duration_ts":72192,"duration":"5.875000","bit_rate":"521597","nb_frames":"141","disposition":{"default":1,"dub":0,"original":0,"comment":0,"lyrics":0,"karaoke":0,"forced":0,"hearing_impaired":0,"visual_impaired":0,"clean_effects":0,"attached_pic":0},"tags":{"language":"eng","handler_name":"VideoHandler"}}

  The output video being played without any problem, on many different devices and OSes including different iOs and androids, but Samsung S5300 doesn't play it. From the device log I can see the following exception :

  E/AwesomePlayer( 1349): This resolution [324X576] Not Supported

  But, when I change the width and height to 576x324 the video can be played on S5300, but in wrong rotation.
  What should I add in ffmpeg parameters to make it play in correct orientation ?

  Thanks

  I want to treanscode RTSP to RTMP to HLS using ffmpeg and nginx_rtmp_module.

  But HLS files(.m3u8, .ts) do not created.

  I’m testing on Docker(amazonlinux image).

  I can access and play rtmp://localhost:1935/live/camera1 by VLC Player, but can not access http://localhost:8088/live/camera1.m3u8.
