How can I get the resolution (width and height) for a video file from a linux command line?

Question

I've been digging through the mplayer/mencoder and ffmpeg documentation and I can't seem to come up with anything. I'm not especially picky as to the output format as I can use a regular expression to pull it out, I just can't seem to get the data in the first place.

Use ffprobe (part of FFmpeg toolkit)

example:

ffprobe -v quiet -print_format json -show_format -show_streams ~/Movies/big_buck_bunny_720p_5mb.mp4 

output:

{     "streams": [         {             "index": 0,             "codec_name": "h264",             "codec_long_name": "H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10",             "profile": "Main",             "codec_type": "video",             "codec_time_base": "1/50",             "codec_tag_string": "avc1",             "codec_tag": "0x31637661",             "width": 1280,             "height": 720,             "coded_width": 1280,             "coded_height": 720,             "has_b_frames": 0,             "sample_aspect_ratio": "1:1",             "display_aspect_ratio": "16:9",             "pix_fmt": "yuv420p",             "level": 31,             "chroma_location": "left",             "refs": 1,             "is_avc": "1",             "nal_length_size": "4",             "r_frame_rate": "25/1",             "avg_frame_rate": "25/1",             "time_base": "1/12800",             "start_pts": 0,             "start_time": "0.000000",             "duration_ts": 378368,             "duration": "29.560000",             "bit_rate": "1032960",             "bits_per_raw_sample": "8",             "nb_frames": "739",             "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": {                 "creation_time": "1970-01-01 00:00:00",                 "language": "und",                 "handler_name": "VideoHandler"             }         },         {             "index": 1,             "codec_name": "aac",             "codec_long_name": "AAC (Advanced Audio Coding)",             "profile": "LC",             "codec_type": "audio",             "codec_time_base": "1/48000",             "codec_tag_string": "mp4a",             "codec_tag": "0x6134706d",             "sample_fmt": "fltp",             "sample_rate": "48000",             "channels": 6,             "channel_layout": "5.1",             "bits_per_sample": 0,             "r_frame_rate": "0/0",             "avg_frame_rate": "0/0",             "time_base": "1/48000",             "start_pts": 0,             "start_time": "0.000000",             "duration_ts": 1419264,             "duration": "29.568000",             "bit_rate": "383960",             "max_bit_rate": "416704",             "nb_frames": "1386",             "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": {                 "creation_time": "1970-01-01 00:00:00",                 "language": "und",                 "handler_name": "SoundHandler"             }         }     ],     "format": {         "filename": "/Users/farsheed/Movies/big_buck_bunny_720p_5mb.mp4",         "nb_streams": 2,         "nb_programs": 0,         "format_name": "mov,mp4,m4a,3gp,3g2,mj2",         "format_long_name": "QuickTime / MOV",         "start_time": "0.000000",         "duration": "29.568000",         "size": "5253880",         "bit_rate": "1421504",         "probe_score": 100,         "tags": {             "major_brand": "isom",             "minor_version": "512",             "compatible_brands": "isomiso2avc1mp41",             "creation_time": "1970-01-01 00:00:00",             "encoder": "Lavf53.24.2"         }     } }
