Description

Summary of the bug:
m2ts made by ffmpeg cannot well be playbacked with panasonic hdd recoder if -x264opts vbv-maxrate=12000:vbv-bufsize=12000:nal-hrd=vbr is added. stop, playback, and black screen are repeated in movie. Sometimes, movie cannot be playbacked at all.
Sound is correctly playbacked.

On the other hand, a m2ts files made without it by ffmpeg are smoothly playbacked with panasonic hdd recoder.

My step
Step 1
Making m2ts files by ffmpeg
Step 2
Converting the files to AVCHD by multiAVCHD, which uses tsMuxR.

http://www.videohelp.com/tools/multiAVCHD

Step3
Playbaking the AVCHD with Panansonic HDD recorder

  • Component changed from FFmpeg to undetermined

Sorry, I again do not understand the ticket;-(

Why do you want to use "vbv-maxrate=12000:vbv-bufsize=12000:nal-hrd=vbr"?
Or in other words: If it works fine without, why do you believe there is a bug?

And if you can answer the two questions:
Do any of the following (untested) x264 options make a difference (does it work for some but not for others)?
"vbv-maxrate=12000:vbv-bufsize=12000"
"vbv-maxrate=12000:nal-hrd=vbr"
"vbv-bufsize=12000:nal-hrd=vbr"

Replying to cehoyos:

Please don't mind. Probably my explanation is not enough.

Why do you want to use "vbv-maxrate=12000:vbv-bufsize=12000:nal-hrd=vbr"?

In general, nal-hrd=vbr enhances the conmpatibity of a video stream.
And blu-ray needs nal-hrd=vbr. Many AVCHD reproduction equipment, too.

an example in x264(r1480)

x264 --crf 16 --preset veryslow --tune film --weightp 0 --bframes 3 --nal-hrd vbr --vbv-maxrate 40000 --vbv-bufsize 30000 --level 4.1 --keyint 24 --b-pyramid strict --slices 4 --aud --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --sar 1:1 -o

"bluray-compat" of x264 option forces the number of bframe, bpyramid(=normal or strict), weightp(0 or 1), aud=1、and nal-hrd=vbr. Of course, even when using "vbv-maxrate=12000:vbv-bufsize=12000:bluray-compat", the above problem appears.

Or in other words: If it works fine without, why do you believe there is a bug?

When using "vbv-maxrate=12000:vbv-bufsize=12000:nal-hrd=vbr" with handbrake to make mkv or mp4 for converting to AVCHD, no problem.
And I understand nal is addressed in libavformat/avc.c in ffmpeg.

And if you can answer the two questions:
Do any of the following (untested) x264 options make a difference (does it work for some but not for others)?
"vbv-maxrate=12000:vbv-bufsize=12000"

No problem. x264 addresses vbv-maxrate and vbv-bufsize, independent of nal, though both are the parameter of nal.

"vbv-maxrate=12000:nal-hrd=vbr"
"vbv-bufsize=12000:nal-hrd=vbr"

x264 ignore these because nal needs vbv-maxrate and vbv-bufsize.
If you need files and console, I will upload them.

But I cannot identify a cause and if nal is a cause for the above.
Now what I can do is to report facts.

my understanding nal. If wrong, please pointing out.
Nal unit consists of VCL(Video Coding Layer) and non-VCL.
VCL-NAL unit is slice data.
Non-VCL-NAL units are
SEI(Supplemental Enhancement Information)
SPS(Sequence Parameter Set)
PPS(Picture Parameter Set)
AUD(Access Unit Delimiter)
Filler data(since x264 r1480, when using --nal-hrd=cbr)

SEI-NAL can includes some SEI messages
Buffering period
Picture timing
User data registered by ITU-T Recommendation T.35
User data unregistered(the enode settings in x264)
Recovery point(including broken_link_flag)
and so on. omit them because x264 don't use them

SPS is basic information of decoding stream
profile_idc
level_idc
num_ref_frames
pic_width_in_mbs_minus1
pic_height_in_map_units_minus1
frame_mbs_only_flag
mb_adaptive_frame_field_flag(MBAFF)
direct_8x8_inference_flag
frame_cropping_flag
VUI(Video Usability Information)
and so on. omit them

PPS is necessary information for decoing each picture(frame)
entropy_coding_mode_flag(CAVLC/CABAC)
weighted_pred_flag(weightp)
weighted_bipred_flag(weightb)
pic_init_qp_minus26(QP)
chroma_qp_index_offset
deblocking_filter_control_present_flag
constrained_intra_pred_flag
slice and picture corresponding infomation
and so on. omit them

AUD(Access Unit Delimiter)

The order of NAL unit is important, eg、AUD, SPS, PPS, SEI…..
