Mythweb unable to download video (not recordings) over 64.5mb

[Thomas C <notchicken@…>]

Hi,

Mythweb is unable to download vidoes that are over 64.5mb (recordings download/stream just fine)

I first thought it was a config error but just for the heck of it I put a 2.5mb .m4v file (under 64.5mb) in the vidoes/movies folder, clicked on the link in mythweb and it downloaded and started playing successfully.

Clicking on the video links in Safari it downloads 64.5mb for every movie, which are all over 1gb, the 2.5mb .m4v file downloads and plays successfully

Clicking on the video links in firefox however, returns an error page File not found Firefox can't find the file at ​http://192.168.0.100/mythweb/video/stream?Id=312. The 2.5mb .m4v file in mythweb downloads and plays just fine.

Videos mounted at /media/sdb/videos. .m4v files located on sdb under sdb/videos/Movies and sdb/videos/TV folders. The 2.5mb .m4v file downloads fine being placed in sdb/videos, sdb/videos/TV and sdb/videos/Movies

All videos play as expected in mythfrontend.

Anything in the apache error logs?

I have clicked on 5 different videos and the log shows:

I've tried adding:

to the file but made no difference.

Looks like you need to disable output_buffering (which defaults to off in PHP, but may have been turned on by your distro) in your PHP configuration. Please ask for help on mythtv-users mailing list if you have questions about how to do so. If this fixes the issue, please report back, here, and we will close the ticket.

locate php.ini
shows

/etc/php5/apache2/php.ini
/etc/php5/cli/php.ini

I changed
output_buffering = 4096
to
output_buffering = Off
in both of the files then rebooted

still cannot download the videos

[phillip.stanton@…]

This is the problem code in /usr/share/mythtv/mythweb/modules/video/stream.php it does not chunk the data like the recordings stream does.

Send data via the backend

$Master_Host = setting('MasterServerIP'); $port = _or(get_backend_setting('BackendStatusPort', $Master_Host),

get_backend_setting('BackendStatusPort'));

if (stripos($Master_Host,':') !== false) {

$Master_Host = '.$Master_Host.';

} readfile("​http://$Master_Host:$port/Content/GetVideo?Id=".$vid_id);

​http://php.net/manual/en/function.readfile.php

"readfile() will not present any memory issues, even when sending large files, on its own. If you encounter an out of memory error ensure that output buffering is off with ob_get_level()."

Keep looking for something that /is/ enabling output_buffering (and make sure you've properly restarted everything).

[joe.yasi@…]

I'm also running into this problem on Ubuntu 13.04. Output_buffering is turned off. ob_get_level() returns 0 and phpinfo() shows output_buffering no value. What is going on here?

[joe.yasi@…]

Ah, there is a ob_start(); in the mythweb init.php file that is causing this. If I flush the output buffer before the readfile, this works:

while (ob_get_level()) {

ob_end_flush();

}

fixed video stream.php

[awaldram@…]

See attachment

correct file type parsing add avi header type video/x-msvideo correct spelling of application clean object buffer

[Thomas C <notchicken@…>]

Thank you thank you thank you awaldram :-D I've updated the stream.php file, rebooted and its all working as expected :-)

[slavo.fabian@…]

It does not function for me.

I have upgraded mythbuntu 0.25 - there is no stream.php but I can see video in web browser

to 0.26 or 0.27 - new function stream.php but video in web browser do not function.

I changed to your new script, but it did not help me.

0.25 has good video output but bad imdb support 0.26 or 0.27 have better imdb support but no video output.

in all version of mythbuntu you will have to repair some scripts or database to use imdb :-(

I hope 0.28 will be better.

[Frank Phillips <fphillips81@…>]

OP has version 0.26-fixes. This was fixed in mythweb 0.27, same solution as what he proposes. slavo.fabian should ask on mythtv-users or forum for help, not this bug.
