avformat/yuv4mpegdec: increase header limit
Allows demuxing UHD F1000000000:33333333 fps yuvj420p files ffmpeg (at HEAD as of now) is creating this: ``` $ ffmpeg -y -i source.265 /tmp/foo.y4m >& /dev/null ... $ xxd /tmp/raw.y4m |less 00000000: 5955 5634 4d50 4547 3220 5731 3932 3020 YUV4MPEG2 W1920 00000010: 4831 3038 3020 4631 3030 3030 3030 3030 H1080 F100000000 00000020: 303a 3333 3333 3333 3333 2049 7020 4130 0:33333333 Ip A0 00000030: 3a30 2043 3432 306d 7065 6732 2058 5953 :0 C420mpeg2 XYS 00000040: 4353 533d 3432 304d 5045 4732 2058 434f CSS=420MPEG2 XCO 00000050: 4c4f 5252 414e 4745 3d4c 494d 4954 4544 LORRANGE=LIMITED 00000060: 0a46 5241 4d45 0a82 8282 8282 8282 8282 .FRAME.......... ... ``` Which cannot be parsed by the same ffmpeg decoder: ``` $ ffmpeg -i /tmp/foo.y4m /tmp/bar.y4m ... [yuv4mpegpipe @ 0x2b69a40] Header too large. /tmp/foo.y4m: Invalid argument ``` This is kicking the ball (per 0b1ff3265e9bdad3b4b6b97ced2f126cb3599568), but seems to work.
