Need some help in understanding this problem, and if there's any way to avoid it.
I notice some videos got "pressed" after using ffmpeg, even using a simple -map command.
The original video looks like this:
Proper video image
with the video properties (as captured by vlc):
Stream 0
Codec: H264-MPEG-4 AVC (part 10)(avc1)
Language: English
Type: Video
Video resolution: 718x478
Buffer dimensions: 720x480
Frame rate: 23.976215
Decoded format:
Orientation: Top left
Color primaries: ITU-R BT.601 (525 lines, 60 Hz)
Color transfer function: ITU-R BT.709
Color space: ITU-R BT.601 Range
Chroma location: left
Output from ffmpeg:
Stream #0:0(eng): Video: h264 (High), yuv420p(tv, smpte170m/smpte170m/bt709, progressive), 718x478 [SAR 8:9 DAR 2872:2151], SAR 223:251 DAR 80057:59989, 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)
However, after using ffmpeg on the video (to remove an extra subtitle):
ffmpeg -i a.mkv -map 0:v -c:v copy -map 0:a -c:a copy -map 0:2 -c:s copy a1.mkv
The new video (a1.mkv) becomes like this:
"Press video image"
Strange thing is, the video properties remain the same, resolution, scale, etc (based on vlc and ffmpeg output as shown above).
Anyone know why is this and how to avoid it? Is the original video "corrupted" in the first place?
Thanks.
