Blu-ray and MPlayer

Having only experience with DVD so far I'm curious how Blu-ray work with
MPlayer (considering DRM and such). Is there a noticeable difference to
DVD usage?

recent builds have demux_open problem which disappears when built with --enable-debug

I've only noticed this problem in the last 24 hours, building with 
either gcc-4.9 or gcc-4.8 from Debian unstable.

When I try rebuilding with --enable-debug passed to configure, the 
resulting binaries don't have the problem, hence the running the mplayer 
binary built without --enable-debug under gdb:

scanlines/telecine/interlaced lines while watching fast actions?

when I play this DVD, whenever the scene changes fast ( a person waving a
hand), it starts to show interlaced lines/scanlines on the fast-moving
parts ( please see an example in the attached image)

what is this symptom called? how could I fix it?

playing this DVD with a regular home DVD player, or playing it on windows
 both work fine, but not on linux

mpeg2 video failing to decode on current head(s)

Just updated mplayer + its ffmpeg and am getting errors below.

It draws a couple/few frames then stops.

Not that long since I last updated, but going back with mplayer fails to
build with current ffmpeg, and it's 1 am so I gave up :-)

FWIW ffplay with ffmpeg in the same place is working OK.

Bug: mp_image_allocate_planes does not allocate enough memory for YV12 images

I have recently updated to the newest SVN mplayer from a very old
version (built in late 2011), and mplayer crashes on about half of the
videos I tried it with. GDB showed most of the crashes happened during
malloc, so suspecting heap corruption, I ran it in valgrind, and it
detected an invalid write in copy_mpi (libmpcodecs/mp_image.c). I
found that doubling the size of the allocation on line 41, the problem
went away. Obviously, this is not a proper solution, but it does
confirm that there is something wrong with either the buffer size or
the calculations of where the plane pointers are in the image.

Fedora 20, most devices that can be supported should be supported, but
plenty of devices can't be supported.

http://linuxtv.org/wiki/index.php/Hardware_Device_Information

"Digital" devices refer to devices which typically tune to a digital
TV standard, like ATSC for North America, DVB for the rest of the
world, ISDB for the rest of the world that doesn't like to be the rest
of the world.

"Analog" devices refer to devices which capture digitizations of an
analog source, like a camera or S-VIDEO output from your VCR.

Cheers

Recording from tv:// isn't realtime

I have an 8 core CPU that seems fast enough for encoding (I can encode at
more than realtime speed with x264).

But with tv:// recording, I only record at about 0.3x of realtime.

I've tried stuff like
time mencoder tv:// -tv
driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:fps=25:alsa:amode=1:forcechan=2:audiorate=48000:forceaudio:immediatemode=0
-ovc x264 -x264encopts
threads=8:subq=5:8x8dct:frameref=2:bframes=3:b_pyramid=normal:weight_b -oac mp3lame
-lameopts cbr:br=128   -o test.avi 

It works fine, but if I stop it after 1mn, I only get about 20 seconds
worth.

I've tried some options to improve speed, but none seem to help.

Is my speed being throttled by the source somehow?
I can play tv:// with mplayer realtime.

Actually I'd love to use mplayer with -dumpstream, but that doesn't work
for this source type.

Any ideas?

This is what mencoder says when I stop it (video bitrate is low because it's a blue image for testing):

Pos:   5.1s    309f ( 0%) 24.89fps Trem:   0min   0mb  A-V:0.000 [4:128]
Flushing video frames.

I'm not capturing TV, just capturing video input from a camera.
Most of those work with linux (use google to verify).
If you need one with a tuner, I can't help you with that, I haven't done
this in a long time :)

newbie: can mencoder stream to red5 server?

I'm new to mencoder but I have used ffmpeg a lot. I've had success using
mencoder to record from a tv tuner to an avi file with the -o option eg: -o
outfile.mpg dvb://, but I'd like to output to a red5 server instead - the
output url being rtmp://172.16.1.250:1935/live/livestream1. I've tried
'-o rtmp://172.16.1.250:1935/live/livestream1 and the command runs ok but
if I play the output in vlc it's just blackness. Can mencoder output to
red5 (like ffmpeg can) ? if so, what is the correct syntax? thanks for any
help.
