[Libav-user] 981204 - Can't omit data stream

[hamidi]

Given the source video with the following streams:

    Stream #0:0(und): Video: hevc (Main) (hev1 / 0x31766568), yuv420p(tv,
progressive), 694x570 [SAR 16:15 DAR 5552:4275], 261 kb/s, 25 fps, 25 tbr,
12800 tbn, 25 tbc (default)
    Stream #0:1(dan): Audio: mp3 (mp4a / 0x6134706D), 48000 Hz, stereo,
fltp, 128 kb/s (default)
    Stream #0:2(eng): Data: bin_data (text / 0x74786574)

the following command doesn't omit the data stream:

ffmpeg -i input.mp4 -c copy -map 0:0 -map 0:1 output.mp4

Even adding -dn doesn't omit it.

Why?
