I am using a udp video source @ 1080i, 25FPS, 25K bitrate, when I output
into a .ts and use ffprobe the file shows 25 fps, 50 tbr, 90k tbn, 50 tbc
I then change the file extension to be a mov and probe the file i get the
following output 50 fps, 50 tbr, 90k tbn, 50 tbc.
I am using the following command but just changing the file extension
ffmpeg -i udp://@239.200.90.1:11080 -vcodec copy -acodec pcm_s16le -top 1
/tmp/interlaced1080.mov
The output from ffmpeg is the following
Output #0, mov, to '/tmp/interlaced1080.mov':
Metadata:
encoder : Lavf56.40.101
Stream #0:0: Video: h264 (avc1 / 0x31637661), yuv420p, 1920x1080 [SAR
1:1 DAR 16:9], q=2-31, 25 fps, 50 tbr, 90k tbn, 90k tbc
Stream #0:1: Audio: pcm_s16le (sowt / 0x74776F73), 48000 Hz, stereo,
s16, 1536 kb/s
Which displays the it is outputting into the file at 25 fps but this isn't
the same when I use ffprobe on the finished file.
My version and build information is as follows
