Hi Philipp,

Looking at my notes, I've never seen the encoder produce streams with levels 1.1, 1.2, 1.3, 2.1, 2.2, or 4.1. Has anybody else?
On my tests, I only saw 3.1 and 3.2 levels.
Level 4.2 streams can be produced though, just not at realtime speeds.
Also, this encoder control change has no effect unless max is changed as well. I think it should look as follows:
if (ctx->dev->devtype->product == CODA_960) { v4l2_ctrl_new_std_menu(&ctx->ctrls, &coda_ctrl_ops, V4L2_CID_MPEG_VIDEO_H264_LEVEL,
V4L2_MPEG_VIDEO_H264_LEVEL_4_0,
~((1 << V4L2_MPEG_VIDEO_H264_LEVEL_2_0) |
V4L2_MPEG_VIDEO_H264_LEVEL_4_2,
~((1 << V4L2_MPEG_VIDEO_H264_LEVEL_1_0) |
(1 << V4L2_MPEG_VIDEO_H264_LEVEL_2_0) | (1 << V4L2_MPEG_VIDEO_H264_LEVEL_3_0) | (1 << V4L2_MPEG_VIDEO_H264_LEVEL_3_1) | (1 << V4L2_MPEG_VIDEO_H264_LEVEL_3_2) |
(1 << V4L2_MPEG_VIDEO_H264_LEVEL_4_0)),
(1 << V4L2_MPEG_VIDEO_H264_LEVEL_4_0) |
(1 << V4L2_MPEG_VIDEO_H264_LEVEL_4_2)), V4L2_MPEG_VIDEO_H264_LEVEL_4_0); } v4l2_ctrl_new_std(&ctx->ctrls, &coda_ctrl_ops,
You are right.
With Nicolas' original patch I see the following levels being reported:
h264_level 0x00990a67 (menu) : min=0 max=11 default=11 value=11 5: 2 8: 3 9: 3.1 10: 3.2 11: 4
With your proposal I get:
h264_level 0x00990a67 (menu) : min=0 max=13 default=11 value=11 0: 1 5: 2 8: 3 9: 3.1 10: 3.2 11: 4 13: 4.2
I will submit a v3 with your proposal.
Thanks
